XMPP Class

Properties   Methods   Events   Configuration Settings   Errors  

The XMPP Class is used to create a lightweight messaging client using the XMPP (Jabber) protocol.

Syntax

ipworks.Xmpp

Remarks

The XMPP class supports both plaintext and SSL/TLS connections. When connecting over SSL/TLS the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL related settings are also supported via the Config method.

A call to the Connect method will perform the entire logon process after which a Connected event will fire indicating connection status. For simplicity, the entire interface is synchronous; the class will not return until a call is completed.

After a successful connection, the class will automatically begin the process of receiving the user's buddy list. The class will parse the XML as it comes in from the server and will set the appropriate properties. Once the entire buddy list has been retrieved, a Sync event will fire.

Sending a message is as simple as calling a single method. One call to the SendMessage method will cause the class to connect if it has not already done so, send the specified message to a specified user, and return to the original connection state.

The XMPP Class interface supports messaging, list and presence management. Other features of the XMPP protocol are supported through the SendCommand method and PITrail event.

Example (Connecting and Sending a Message)

IMControl.Connect("myusername", "mypassword") IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser") Example (Sending a Single Message)

IMControl.User = "myusername" IMControl.Password = "mypassword" IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser")

Controls how the class authenticates itself with the XMPP server.

Syntax


public String getAuthMethods();


public void setAuthMethods(String authMethods);

Default Value

"*"

Remarks

AuthMethods is a comma-separated list of authentication methods to be enabled on the class, listed in order of preference. When authenticating, the class will pick the first method in the list that is supported by the server.

The special value * (default) may be supplied to cause the class to enable all supported authentication methods in order of presumed security. The XMPP class currently supports the following values for AuthMethods, listed in order of most secure to least secure:

  • SASL/DIGEST-MD5
  • AuthIQ/Digest
  • SASL/PLAIN
  • AuthIQ/Plaintext
  • SASL/NTLM

Buddies Property (XMPP Class)

Collection of buddies in the buddy list.

Syntax


public XMPPBuddyList getBuddies();


Remarks

After a Sync event is fired, this property will contain a collection of all buddies in the buddy list. The buddy list will be updated by the server when a successful call to RetrieveRoster has been made.

This collection is indexed from 0 to size - 1.

This property is read-only.

Connected Property (XMPP Class)

This indicates the class's login status.

Syntax


public boolean isConnected();


public void setConnected(boolean connected);

Default Value

False

Remarks

This value shows whether or not the class has successfully logged into the IMServer. It will not be true until a successful Connected event has fired.

Note: It is recommended to use the Connect or Disconnect method instead of setting this property.

This property is not available at design time.

Firewall Property (XMPP Class)

A set of properties related to firewall access.

Syntax


public Firewall getFirewall();


public void setFirewall(Firewall firewall);

Remarks

This is a Firewall type property which contains fields describing the firewall through which the class will attempt to connect.

IMPort Property (XMPP Class)

The server port for XMPP (default 5222).

Syntax


public int getIMPort();


public void setIMPort(int IMPort);

Default Value

5222

Remarks

For implicit SSL, use port 5223 (please refer to the SSLStartMode property for more information).

A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is attempted and cannot be changed once a connection is established. Any attempt to change this property while connected will fail with an error.

IMServer Property (XMPP Class)

This is the instant messaging server.

Syntax


public String getIMServer();


public void setIMServer(String IMServer);

Default Value

""

Remarks

This is the instant messaging server to which the class will connect when the Connect method is called. The IMServer property must contain a valid XMPP (Jabber) server, or any subsequent calls to the Connect method will fail.

LocalDirectory Property (XMPP Class)

The directory to which received files are saved.

Syntax


public String getLocalDirectory();


public void setLocalDirectory(String localDirectory);

Default Value

""

Remarks

This setting specifies the directory on disk to which received files will be saved. If this property is not set and a file is received the file data will be available through the Transfer event parameters. This property may also be set when the StartTransfer event fires.

LocalFile Property (XMPP Class)

The path to the file that will be sent.

Syntax


public String getLocalFile();


public void setLocalFile(String localFile);

Default Value

""

Remarks

This property specifies the local file that will be sent when calling SendFile. This property must be set before calling SendFile.

LocalHost Property (XMPP Class)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax


public String getLocalHost();


public void setLocalHost(String localHost);

Default Value

""

Remarks

The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

MessageHTML Property (XMPP Class)

This is the HTML version of the current message.

Syntax


public String getMessageHTML();


public void setMessageHTML(String messageHTML);

Default Value

""

Remarks

If the user wishes to send any HTML as a part of the message, it must be set in the MessageHTML property. The HTML must be an entire HTML document, including the <html> and <body> tags. If the HTML has unbalanced tags, the XMPP class will fail with an error.

This property is not available at design time.

MessageOtherData Property (XMPP Class)

This property is not available at design time.

MessageText Property (XMPP Class)

This is the plain text of the current message.

Syntax


public String getMessageText();


public void setMessageText(String messageText);

Default Value

""

Remarks

MessageText is the plain text version of the current message, taken from the message's "body" child element. The text in this property is automatically escaped to ensure valid XML parsing on the other end.

This property is not available at design time.

MessageThread Property (XMPP Class)

This is the thread name of the current message.

Syntax


public String getMessageThread();


public void setMessageThread(String messageThread);

Default Value

""

Remarks

MessageThread will contain the name of the thread associated with the message. Threads are useful for tracking messages of type "chat" or "groupchat".

This property is not available at design time.

MessageType Property (XMPP Class)

This is the type of the current message.

Syntax

error (jmtError - 4)A message returned to a sender specifying an error associated with a previous message sent by the sender to an intended recipient.

This property is not available at design time.

Password Property (XMPP Class)

This is the user's password.

Syntax


public String getPassword();


public void setPassword(String password);

Default Value

""

Remarks

This must be set before a connection is attempted. If a call to the Connect method is made specifying a password, the Password property will contain that password.

Presence Property (XMPP Class)

This is the availability of the entity.

Syntax


public int getPresence();


public void setPresence(int presence);

Enumerated values:
  public final static int pcOffline = 0;

  public final static int pcChat = 1;

  public final static int pcAway = 2;

  public final static int pcXA = 3;

  public final static int pcDND = 4;

Default Value

1

Remarks

When the class completes the initial log in, it will send information telling other entities subscribed to this entity's presence that it is online. The application must provide different status and availability information as the user changes them.

The Presence property has one of four values representing general information about the user's status as defined in the Jabber protocol specification:

pcOffline (0)Invisible: JabberId is offline.
pcChat (1)Available: JabberId is online.
pcAway (2)Away: JabberId is online, but the user is away from their computer.
pcXA (3)Extended Away: JabberId is online, but the user is away from their computer for an extended period of time.
pcDND (4)Do not Disturb: JabberId is online, but is busy and does not wish to be disturbed.

By default, the class sets the client presence to pcChat, meaning that the user is available. To change the initial status sent by the class set Presence to the desired presence before calling Connect.

Note: offline is not officially supported by the XMPP specification, however some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an Error.

The Status property is a pure-text string representing the user's presence information. Its value maybe be any random string, including the empty string, "".

Whenever the value in Presence or Status are changed, the class will send that information to the server. If the application or user wishes to associate a specific status message with a new presence value, it should use the ChangePresence method. ChangePresence will update both the Presence and Status properties, and then send that information to the server.

Note: It is recommended to use the ChangePresence method instead of setting this property.

This property is not available at design time.

Resource Property (XMPP Class)

This is the resource for the current session.

Syntax


public String getResource();


public void setResource(String resource);

Default Value

"IPWorks XMPP Agent"

Remarks

Whenever an entity logs in to an XMPP (Jabber) server, it must provide account information as well as a resource. Resources allow multiple clients to log in using the same account. The server will forward all messages and PI data aimed at a specific resource to that resource. If a command or message is to be sent to a Jabber ID with no specified resource, the server will push that command or message out to all connected resources.

ServerDomain Property (XMPP Class)

The XMPP server's domain.

Syntax


public String getServerDomain();


public void setServerDomain(String serverDomain);

Default Value

""

Remarks

The domain of the XMPP server itself. Set this value if the domain of the server is different from the DNS name of the IMServer.

SSLAcceptServerCert Property (XMPP Class)

Instructs the class to unconditionally accept the server certificate that matches the supplied certificate.

Syntax


public Certificate getSSLAcceptServerCert();


public void setSSLAcceptServerCert(Certificate SSLAcceptServerCert);

Remarks

If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Please note that this functionality is provided only for cases where you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

SSLCert Property (XMPP Class)

The certificate to be used during SSL negotiation.

Syntax


public Certificate getSSLCert();


public void setSSLCert(Certificate SSLCert);

Remarks

The digital certificate that the class will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the Encoded field to the encoded certificate. To select a certificate, use the store and subject fields.

SSLEnabled Property (XMPP Class)

Whether TLS/SSL is enabled.

Syntax


public boolean isSSLEnabled();


public void setSSLEnabled(boolean SSLEnabled);

Default Value

False

Remarks

This setting specifies whether TLS/SSL is enabled in the class. When False (default) the class operates in plaintext mode. When True TLS/SSL is enabled.

TLS/SSL may also be enabled by setting SSLStartMode. Setting SSLStartMode will automatically update this property value.

This property is not available at design time.

SSLProvider Property (XMPP Class)

TBD.

Syntax


public int getSSLProvider();


public void setSSLProvider(int SSLProvider);

Enumerated values:
  public final static int sslpAutomatic = 0;

  public final static int sslpPlatform = 1;

  public final static int sslpInternal = 2;

Default Value

0

Remarks

TBD.

SSLServerCert Property (XMPP Class)

The server certificate for the last established connection.

Syntax


public Certificate getSSLServerCert();


Remarks

SSLServerCert contains the server certificate for the last established connection.

SSLServerCert is reset every time a new connection is attempted.

This property is read-only.

SSLStartMode Property (XMPP Class)

Determines how the class starts the SSL negotiation.

Syntax


public int getSSLStartMode();


public void setSSLStartMode(int SSLStartMode);

Enumerated values:
  public final static int sslAutomatic = 0;

  public final static int sslImplicit = 1;

  public final static int sslExplicit = 2;

  public final static int sslNone = 3;

Default Value

3

Remarks

The SSLStartMode property may have one of the following values:

0 (sslAutomatic)If the remote port is set to the standard plaintext port of the protocol (where applicable), the class will behave the same as if SSLStartMode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit).
1 (sslImplicit)The SSL negotiation will start immediately after the connection is established.
2 (sslExplicit)The class will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS.
3 (sslNone - default)No SSL negotiation, no SSL security. All communication will be in plaintext mode.

Status Property (XMPP Class)

Description of the availability of this entity.

Syntax


public String getStatus();


public void setStatus(String status);

Default Value

"Available for Chat."

Remarks

When the class completes the initial log in, it will send information telling other entities subscribed to this entity's presence that it is online. The application must provide different status and availability information as the user changes them.

The Presence property has one of four values representing general information about the user's status as defined in the Jabber protocol specification:

pcOffline (0)Invisible: JabberId is offline.
pcChat (1)Available: JabberId is online.
pcAway (2)Away: JabberId is online, but the user is away from their computer.
pcXA (3)Extended Away: JabberId is online, but the user is away from their computer for an extended period of time.
pcDND (4)Do not Disturb: JabberId is online, but is busy and does not wish to be disturbed.

By default, the class sets the client presence to pcChat, meaning that the user is available. To change the initial status sent by the class set Presence to the desired presence before calling Connect.

Note: offline is not officially supported by the XMPP specification, however some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an Error.

The Status property is a pure-text string representing the user's presence information. Its value maybe be any random string, including the empty string, "".

Whenever the value in Presence or Status are changed, the class will send that information to the server. If the application or user wishes to associate a specific status message with a new presence value, it should use the ChangePresence method. ChangePresence will update both the Presence and Status properties, and then send that information to the server.

Note: It is recommended to use the ChangePresence method instead of setting this property.

This property is not available at design time.

Timeout Property (XMPP Class)

A timeout for the class.

Syntax


public int getTimeout();


public void setTimeout(int timeout);

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the class throws an exception.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

User Property (XMPP Class)

The user portion of this entity's Jabber ID.

Syntax


public String getUser();


public void setUser(String user);

Default Value

""

Remarks

The User property is a unique username associated with this entity and set at time of registration under the field "user".

UserDomain Property (XMPP Class)

Gets or sets the domain value used for Jabber IDs.

Syntax


public String getUserDomain();


public void setUserDomain(String userDomain);

Default Value

""

Remarks

A Jabber ID (JID) is a unique identifier of the format "User@Domain/Resource". user@domain denotes the account by username and domain. The Resource is given during the login process to distinguish individual connections under the same account. If the IMServer contains multiple domains, this property setting allows the user to specify the domain under which to login.

If Domain is empty, the value in IMServer is used by default when creating the client's JID.

UserInfo Property (XMPP Class)

Collection of named registration fields.

Syntax


public XMPPUserInfoMap getUserInfo();


public void setUserInfo(XMPPUserInfoMap userInfo);

Remarks

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the UserInfo collection accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

instructionsSpecial instructions sent from the server.
usernameThe username to be associated with this account.
passwordThe initial password for this account.
nameThe user's name.
emailThe user's email address.
addressThe user's physical address.
cityThe user's city of residence.
stateThe user's state (for United States citizens).
zipThe user's postal code (for United States citizens).
phoneThe user's phone number.
URLThe user's website.
dateThe date of registration.
miscAny miscellaneous data.
textAny extra text (potentially for a personal bio).
removeSpecifies a request to unregister.

After the user has set all of the values in UserInfo, and added any extra fields they may wish to include in their registration, the application should make a call to Register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

This collection is a hashtable type of collection where the field string is used as the key to the desired XMPP user info object.

Example (Setting New User Information)

xmpp1.queryRegister("server"); xmpp1.getUserInfo().item("Username").setValue("newuser"); xmpp1.getUserInfo().item("Password").setValue("newpass"); xmpp1.register("server");

This property is not available at design time.

Add Method (Xmpp Class)

This method will add an entity to this entity's roster.

Syntax

public void add(String jabberId, String name, String groups);

Remarks

JabberId is the Jabber ID of the entity to be added. It should be of form "user@host". If no hostname is specified, the class will assume the user's account is with the server in IMServer, and will append that hostname to JabberId before sending the request.

Name will contain the name that is to be associated with JabberId in this entity's roster. It may be the empty string, "".

Groups is either the empty string ("") or a comma- separated list of groups to which JabberId is to be added. If JabberId already exists in the buddy list, it will be updated to exist only in the specified groups. A buddy's group list can also be modified by the Buddies property.

The Add method will make a subscription request to the presence of the specified JabberId. Upon receiving this request, the server will add an entry into this user's buddy list with a subscription of type subscriptionNone (0) if there was no previous entry (if this user has already allowed JabberId to subscribe to this user's presence, there will already be an entry of type subscriptionFrom (2)). If the contact chooses to allow the subscription, the server will update the entry and a BuddyUpdate event will fire with the new subscription value (subscriptionTo (1) if this is a new contact, or subscriptionBoth (3) if the contact is now mutual).

The XMPP protocol permits XMPP (Jabber) clients to communicate with foreign IM networks such as AIM, MSN, SMS, and others through the use of gateway servers that translate between the foreign protocol and XMPP. When sending or receiving presence information, messages, or subscription requests, Domain will be a gateway for the foreign network on which the contact resides and with which this user has registered an account for that foreign network. The Register method can be used to register with a foreign network gateway.

Cancel Method (Xmpp Class)

This will cancel another entity's subscription to this entity's presence.

Syntax

public void cancel(String jabberId);

Remarks

If for any reason the user should want to undo a previously granted subscription, this can be achieved through the Cancel method. The method will unsubscribe the target from this user's presence, thus preventing the target from seeing this user in the future.

ChangePassword Method (Xmpp Class)

This method will change the current user's password.

Syntax

public void changePassword(String password);

Remarks

This method changes the current user's password to the password that is specified. The class must be connected to the server when this method is called.

ChangePresence Method (Xmpp Class)

This method will set the availability and status of this entity.

Syntax

public void changePresence(int presenceCode, String status);

Remarks

PresenceCode should correspond the possible values of the Presence property:

pcOffline (0)Invisible: JabberId is offline.
pcChat (1)Available: JabberId is online.
pcAway (2)Away: JabberId is online, but the user is away from their computer.
pcXA (3)Extended Away: JabberId is online, but the user is away from their computer for an extended period of time.
pcDND (4)Do not Disturb: JabberId is online, but is busy and does not wish to be disturbed.

By default, the class sets the client presence to pcChat, meaning that the user is available. To change the initial status sent by the class set Presence to the desired presence before calling Connect.

Note: offline is not officially supported by the XMPP specification, however some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an Error.

Status can be any random string, including the empty string "".

Config Method (Xmpp Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Connect Method (Xmpp Class)

This method will connect the class to the server.

Syntax

public void connect();

Remarks

The Connect method performs the entire connection routine. This includes connection to the IMServer, authenticating with the specified User and Password, and session initialization.

The Connected event will fire once for the initial TCP connection and again when the XMPP Logon is complete.

ConnectTo Method (Xmpp Class)

This method will connect the class to the server.

Syntax

public void connectTo(String user, String password);

Remarks

The Connect method performs the entire connection routine. This includes connection to the IMServer, user logon and authentication, and session initialization.

The Connected event will fire once for the initial TCP connection and again when the XMPP Logon is complete.

Since Connect is called with a user and password specified, the User and Password properties will updated accordingly.

Disconnect Method (Xmpp Class)

This method disconnects the class from the server.

Syntax

public void disconnect();

Remarks

The Disconnect method will send the disconnect command to the notification server. Upon disconnection, a Disconnected event will be fired.

DoEvents Method (Xmpp Class)

This method processes events from the internal message queue.

Syntax

public void doEvents();

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Interrupt Method (Xmpp Class)

Interrupt the current method.

Syntax

public void interrupt();

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ProbePresence Method (Xmpp Class)

Use this method to probe for another entity's presence.

Syntax

public void probePresence(String jabberId);

Remarks

In the case that the user needs to update a particular entity's presence this method can be used to retrieve it. After a successful call, the server will either respond with the last known presence for Jabber, or will send a presence element of type "error". In either case, the respond will be returned by a Presence event.

QueryRegister Method (Xmpp Class)

This method queries a server for the necessary registration fields.

Syntax

public void queryRegister(String XMPPServer);

Remarks

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the UserInfo collection accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

instructionsSpecial instructions sent from the server.
usernameThe username to be associated with this account.
passwordThe initial password for this account.
nameThe user's name.
emailThe user's email address.
addressThe user's physical address.
cityThe user's city of residence.
stateThe user's state (for United States citizens).
zipThe user's postal code (for United States citizens).
phoneThe user's phone number.
URLThe user's website.
dateThe date of registration.
miscAny miscellaneous data.
textAny extra text (potentially for a personal bio).
removeSpecifies a request to unregister.

After the user has set all of the values in UserInfo, and added any extra fields they may wish to include in their registration, the application should make a call to Register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

Register Method (Xmpp Class)

This method registers an account with a server.

Syntax

public void register(String XMPPServer);

Remarks

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the UserInfo collection accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

instructionsSpecial instructions sent from the server.
usernameThe username to be associated with this account.
passwordThe initial password for this account.
nameThe user's name.
emailThe user's email address.
addressThe user's physical address.
cityThe user's city of residence.
stateThe user's state (for United States citizens).
zipThe user's postal code (for United States citizens).
phoneThe user's phone number.
URLThe user's website.
dateThe date of registration.
miscAny miscellaneous data.
textAny extra text (potentially for a personal bio).
removeSpecifies a request to unregister.

After the user has set all of the values in UserInfo, and added any extra fields they may wish to include in their registration, the application should make a call to Register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

A new account can be registered at any time, including while the class is logged into the host under an existing account.

Remove Method (Xmpp Class)

This method will remove an entity from this entity's roster.

Syntax

public void remove(String jabberId, String name, String group);

Remarks

JabberId is the Jabber ID of the entity to be removed. It should be of form "user@host". If no hostname is specified, the class will assume the user's account is with the server in IMServer, and will append that hostname to JabberId before sending the request.

Name should contain the name that is to be associated with JabberId in this entity's roster. It may be the empty string, "".

Groups may be either the empty string ("") or a comma- separated list of groups from which JabberId is to be removed. If no group is specified, the buddy will be completely removed from the buddy list.

After calling the Remove method, the server will remove the entry from the server-side roster, and will push the result out to all connected resources. A BuddyUpdate event will fire with subscription of type subscriptionRemove, and the entry will be removed from the Jabber class's internally stored list.

Reset Method (Xmpp Class)

Reset the class.

Syntax

public void reset();

Remarks

This method will reset the class's properties to their default values.

RetrieveRoster Method (Xmpp Class)

This method will retrieve this entity's roster from the server.

Syntax

public void retrieveRoster();

Remarks

After the class connects, it will automatically send a request to the server to retrieve the roster. However, should the user or application wish to update the entire roster, this method may be used to do so.

After a successful call to the RetrieveRoster method, the server will respond with this entity's roster. The class will parse the roster and fire the Sync event once per item. This event may also fire for each entity added to or removed from the roster.

SendCommand Method (Xmpp Class)

This method sends a command to the server.

Syntax

public void sendCommand(String command);

Remarks

The SendCommand method will send the Command parameter to the server. The command must be in valid XML format, and must be recognizable to the IMServer.

The SendCommand method should only be used by programmers or users who are connecting to non-standard servers whose command list is not covered by the class. Any responses that are defined in the protocol specification will be returned by the appropriate event. Any non-standard IQ message will be returned by the IQ event. All other responses will be returned by the PITrail event.

SendFile Method (Xmpp Class)

Sends a file to the specified user.

Syntax

public void sendFile(String jabberId);

Remarks

This method sends the file specified by LocalFile to the user specified by the JabberId parameter.

JabberId is the intended recipient of the message. It is of the form user@domain/resource. If a resource is not supplied, all logged-in instances of the user's account will receive the message.

If SetSendStream is called, the stream will be used as the source when sending the file.

The class supports sending files using In-Band Bystestreams as defined in XEP-0047 and XEP-0096.

SendMessage Method (Xmpp Class)

This method will send a message to the specified user.

Syntax

public String sendMessage(String jabberId);

Remarks

JabberId is the intended recipient of the message. It is of the form user@domain/resource. If a resource is not supplied, all logged-in instances of the user's account will receive the message.

The class associates several properties with messages it receives and sends. When it receives a message, the class will parse out the corresponding values and set these properties before firing a MessageIn event. After the event returns control to the class, the properties will be cleared (ie, they will be set to the empty string, "").

Before sending a message, the application should set the appropriate properties to be associated with the message. The class will send only properties with non-empty string values (""), and will clear all properties after a successful send.

The associated properties are the following:

MessageTypethe type of the message to be sent
MessageSubjectfor "headline" type messages, this is the subject
MessageThreadfor "chat" type messages, this is the thread on which the current message is a follow-up
MessageTextthe plain text of the message
MessageHTMLthe HTML version of the message
MessageOtherDataany extra data associated with the message but not required by the protocol.

If the parameter passed to SendMessage is prefixed with "@" the component will interpret the value as a domain when constructing the message. This allows for sending directly to sub-domains.

Note: the XMPP class will generate and return a unique identifier for each message sent. This identifier can be used to track messages in conjunction with various Jabber Extension Protocols.

SetReceiveStream Method (Xmpp Class)

Sets the stream to which the received file data from will be written.

Syntax

public void setReceiveStream(java.io.OutputStream receiveStream);

Remarks

This method sets the stream to which the incoming file will be written. This can be set from within the StartTransfer event when a file is received.

The file data will be written to the stream. The stream should be open and normally set to position 0. The class will automatically close this stream if CloseStreamAfterTransfer is true (default). The downloaded content will be written starting at the current position in the stream.

If a download stream is set, the incoming file will not be written to LocalDirectory.

SetSendStream Method (Xmpp Class)

Sets the stream to be sent.

Syntax

public void setSendStream(java.io.InputStream sendStream, String filename);

Remarks

This method sets the stream to be sent to the recipient. Filename specifies the name of the file. If an upload stream is set before the SendFile method is called, the content of the stream will be read by the class and sent. The stream should be open and normally set to position 0.

The class will automatically close this stream if CloseStreamAfterTransfer is true (default). If the stream is closed, you will need to call SetSendStream again before calling SendFile again.

The content of the stream will be read from the current position all the way to the end.

Note: SetSendStream and LocalFile will reset the other.

SetUserInfoField Method (Xmpp Class)

This method will add a user information field for registration.

Syntax

public void setUserInfoField(String field, String value);

Remarks

This method will search through UserInfo for the field name in Field and set the corresponding value to Value. If the field was not previously contained in UserInfo, it will automatically added.

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the UserInfo collection accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

instructionsSpecial instructions sent from the server.
usernameThe username to be associated with this account.
passwordThe initial password for this account.
nameThe user's name.
emailThe user's email address.
addressThe user's physical address.
cityThe user's city of residence.
stateThe user's state (for United States citizens).
zipThe user's postal code (for United States citizens).
phoneThe user's phone number.
URLThe user's website.
dateThe date of registration.
miscAny miscellaneous data.
textAny extra text (potentially for a personal bio).
removeSpecifies a request to unregister.

After the user has set all of the values in UserInfo, and added any extra fields they may wish to include in their registration, the application should make a call to Register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

SubscribeTo Method (Xmpp Class)

Use this method to subscribe to another entity's presence.

Syntax

public void subscribeTo(String jabberId);

Remarks

This method will send a request for a subscription to JabberId's presence. If the entity allows the subscription, a new item will be stored in the buddy list with the appropriate subscription type. Otherwise, no change will take place.

Unregister Method (Xmpp Class)

This method cancels an account with the host.

Syntax

public void unregister();

Remarks

If the user or application wishes to terminate an account with the IMServer it should make a call to this method. After a successful call, the account will be canceled and the class will be logged off the server, but not disconnected.

UnsubscribeTo Method (Xmpp Class)

This method will cancel a subscription to another entity's presence.

Syntax

public void unsubscribeTo(String jabberId);

Remarks

This method will inform the server of the cancellation of subscription to JabberId's presence. After a successful call the subscription type of the associated buddy list item will be updated.

UpdateBuddyGroup Method (Xmpp Class)

Updates the buddy's associatd groups.

Syntax

public void updateBuddyGroup(int buddyIndex, String group);

Remarks

This method updates the associated groups for the buddy specified by BuddyIndex.

After the Sync event has fired the Group field is populated with a comma-separated list of groups for each buddy. To update the groups for a buddy call this method with the buddy's index and the comma-separate list of groups the buddy should be associated with. Setting Group to empty string ("") will cause the buddy to be completely disassociated from all groups.

BuddyUpdate Event (Xmpp Class)

This event is fired whenever a roster entry is updated.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void buddyUpdate(XmppBuddyUpdateEvent e) {}
  ...
}

public class XmppBuddyUpdateEvent {
  public int buddyIdx;

}

Remarks

The BuddyUpdate event will fire whenever a new buddy list entry is added or an old entry is updated. The updated information can be retrieved through the Buddies collection property. The BuddyIdx parameter of this event will be the index of that XMPPBuddy in the collection.

Connected Event (Xmpp Class)

This event is fired when a connection to the IM Server is completed.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void connected(XmppConnectedEvent e) {}
  ...
}

public class XmppConnectedEvent {
  public int statusCode;

  public String description;

}

Remarks

If the connection is made normally, StatusCode is 0, and Description is "OK".

If the connection fails, StatusCode has the error code returned by the TCP/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.

Please refer to the Error Codes section for more information.

ConnectionStatus Event (Xmpp Class)

Fired to indicate changes in connection state.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void connectionStatus(XmppConnectionStatusEvent e) {}
  ...
}

public class XmppConnectionStatusEvent {
  public String connectionEvent;

  public int statusCode;

  public String description;

}

Remarks

The ConnectionStatus event is fired when the connection state changes: completion of a firewall or proxy connection, completion of a security handshake, etc.

The ConnectionEvent parameter indicates the type of connection event. Values may include:

Firewall connection complete.
SSL or S/Shell handshake complete (where applicable).
Remote host connection complete.
Remote host disconnected.
SSL or S/Shell connection broken.
Firewall host disconnected.

StatusCode has the error code returned by the TCP/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.

Disconnected Event (Xmpp Class)

This event is fired when the chat service connection is lost.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void disconnected(XmppDisconnectedEvent e) {}
  ...
}

public class XmppDisconnectedEvent {
  public int statusCode;

  public String description;

}

Remarks

If the connection is broken normally, StatusCode is 0, and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the TCP/IP subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error.

Please refer to the Error Codes section for more information.

EndTransfer Event (Xmpp Class)

Fired when a file transfer completes.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void endTransfer(XmppEndTransferEvent e) {}
  ...
}

public class XmppEndTransferEvent {
  public int direction;

  public String fileId;

  public String filename;

  public boolean success;

}

Remarks

When a file transfer completes this event will fire.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (Xmpp Class)

This event is fired when the server sends a protocol error message.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void error(XmppErrorEvent e) {}
  ...
}

public class XmppErrorEvent {
  public int errorCode;

  public String description;

}

Remarks

This is fired whenever there is a protocol error. ErrorCode will contain the error code string sent by the server. Description will contain the Xmpp class's interpretation of the code.

IQ Event (Xmpp Class)

This event is fired for IQ messages not normally supported by the class.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void IQ(XmppIQEvent e) {}
  ...
}

public class XmppIQEvent {
  public String iq;

  public String id;

  public String from;

  public String iqType;

  public boolean ignore;

}

Remarks

Some servers may wish to gather some data from the client in ways not specified by the XMPP RFC. This event will contain any IQ message that is not a part of the Jabber specification. The Iq parameter will contain an entire XML entity, and thus will require both knowledge of XML and knowledge of the possible contents of the IQ message to parse. Id will contain the transaction id of the IQ message. From will contain the sender's Jabber ID. IqType will have one of the following values:

"get"The IQ is requesting information from this XMPP client.
"set"The IQ is attempting to set a value..
"result"The IQ is a success response to a previous IQ.
"error"The IQ is an error response to a previous IQ.

Note: to respond to these IQs, you may use the SendCommand method.

MessageIn Event (Xmpp Class)

This event is fired upon receipt of a message.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void messageIn(XmppMessageInEvent e) {}
  ...

  public String messageId;

  public String from;

  public String domain;

  public String resource;

  public int messageType;

  public String subject;

  public String messageThread;

  public String messageText;

  public String messageHTML;

  public String other;

}

Remarks

When a message is received, the XMPP class will parse the sender's Jabber ID into the From, Domain, and Resource fields. These parameters can be used to track the exact instance of a user's account that originated the message.

MessageId can be used with Jabber extension protocols. The MessageText parameter is the plaintext portion of the message body. MessageHTML will contain any HTML from the message.

Type the type of message received. See MessageType for a list of possible values. For message of type "headline", Subject will reflect the subject of the message. For messages of type "chat", Thread will report the conversation thread for which the current message is a follow-up.

Other will contains any extra data associated with the message but not defined by the XMPP-IM protocol.

PITrail Event (Xmpp Class)

This event is fired for all protocol messages.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void PITrail(XmppPITrailEvent e) {}
  ...
}

public class XmppPITrailEvent {
  public int direction;

  public String pi;

}

Remarks

The PITrail event is useful for debugging purposes. It shows all the interaction between the client and the server, line by line.

SessionId will hold the session number that originated the PI. A value of 0 is reserved for all PI dealing with the IMServer.

The direction parameter shows the originator of the message:

0 (Client)Pi originates from the client.
1 (Server)Pi originates from the server.
2 (Info)Pi is an informative message originating from within the class.

The Pi parameter contains the PI message.

Presence Event (Xmpp Class)

This event is fired when the presence of a subscribed entity changes.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void presence(XmppPresenceEvent e) {}
  ...
}

public class XmppPresenceEvent {
  public String user;

  public String domain;

  public String resource;

  public int availability;

  public String status;

}

Remarks

This event contains the availability and status information of a particular Jabber entity to whom this entity has a subscription.

Because a user can log in multiple times using the same account, the XMPP class will parse the user's Jabber ID into the User, Domain and Resource parameters so that the client can easily track which instance of the account sent the presence.

The XMPP protocol permits XMPP (Jabber) clients to communicate with foreign IM networks such as AIM, MSN, SMS, and others through the use of gateway servers that translate between the foreign protocol and XMPP. When sending or receiving presence information, messages, or subscription requests, Domain will be a gateway for the foreign network on which the contact resides and with which this user has registered an account for that foreign network. The Register method can be used to register with a foreign network gateway.

Availability corresponds to the Presence property of the class, with the same possible values:

pcOffline (0)Invisible: JabberId is offline.
pcChat (1)Available: JabberId is online.
pcAway (2)Away: JabberId is online, but the user is away from their computer.
pcXA (3)Extended Away: JabberId is online, but the user is away from their computer for an extended period of time.
pcDND (4)Do not Disturb: JabberId is online, but is busy and does not wish to be disturbed.

By default, the class sets the client presence to pcChat, meaning that the user is available. To change the initial status sent by the class set Presence to the desired presence before calling Connect.

Note: offline is not officially supported by the XMPP specification, however some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an Error.

Status corresponds to the Status property. This value may be any random string, including the empty string, "".

ReadyToSend Event (Xmpp Class)

Fired when the class is ready to send data.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void readyToSend(XmppReadyToSendEvent e) {}
  ...
}

public class XmppReadyToSendEvent {
}

Remarks

The ReadyToSend event indicates that the underlying TCP/IP subsystem is ready to accept data after a failed DataToSend. The event is also fired immediately after a connection to the remote host is established.

SSLServerAuthentication Event (Xmpp Class)

Fired after the server presents its certificate to the client.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void SSLServerAuthentication(XmppSSLServerAuthenticationEvent e) {}
  ...
}

public class XmppSSLServerAuthenticationEvent {
  public byte[] certEncoded;

  public String certSubject;

  public String certIssuer;

  public String status;

  public boolean accept;

}

Remarks

This event is where the client can decide whether to continue with the connection process or not. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (Xmpp Class)

Shows the progress of the secure connection.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void SSLStatus(XmppSSLStatusEvent e) {}
  ...
}

public class XmppSSLStatusEvent {
  public String message;

}

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

StartTransfer Event (Xmpp Class)

Fired when a file transfer begins.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void startTransfer(XmppStartTransferEvent e) {}
  ...
}

public class XmppStartTransferEvent {
  public int direction;

  public String fileId;

  public String user;

  public String domain;

  public String resource;

  public String filename;

  public String datetime;

  public long size;

  public boolean accept;

}

Remarks

When a file is received, the XMPP component will parse the sender's Jabber ID into the User, Domain, and Resource fields. The FileId and Filename parameters identify the current transfer. Within this event you may override the Filename by setting the Filename parameter. At this time you may also set LocalDirectory if it is not already set or call SetReceiveStream.

When a sending a file, the XMPP component will parse the receiver's Jabber ID into the User, Domain, and Resource fields.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

SubscriptionRequest Event (Xmpp Class)

This event fires when a subscription request is received.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void subscriptionRequest(XmppSubscriptionRequestEvent e) {}
  ...
}

public class XmppSubscriptionRequestEvent {
  public String from;

  public String domain;

  public boolean accept;

}

Remarks

This event fires whenever another XMPP entity requests a subscription to this entity's presence. The XMPP class will parse the requesting entity's Jabber ID into the From and Domain parameters. There is no need to know which resource sent the request, since all instances of the requesting entity's account have access to the same roster.

Accept will initially be false, but setting it to true will cause the XMPP class to allow the remote subscription. Otherwise, the XMPP class will actively deny the subscription request.

Sync Event (Xmpp Class)

This event fires upon a complete information synchronization with the server.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void sync(XmppSyncEvent e) {}
  ...
}

public class XmppSyncEvent {
}

Remarks

The Sync event will fire after each successful call to the RetrieveRoster method. When the event fires, the buddy list, or roster, will be completely retrieved and the Buddies collection will be filled out accordingly:

Id the jabber ids associated with the buddies
Group the group associated with each entry (if a buddy is in more than one group, they will have multiple entries in the buddy list)
Subscription the subscription type for each buddy

Please refer to Buddies collection property for more information.

Transfer Event (Xmpp Class)

Fired during file transfer.

Syntax

public class DefaultXmppEventListener implements XmppEventListener {
  ...
  public void transfer(XmppTransferEvent e) {}
  ...
}

public class XmppTransferEvent {
  public int direction;

  public String fileId;

  public String filename;

  public long bytesTransferred;

  public int percentDone;

  public byte[] text;

  public boolean cancel;

}

Remarks

This event will fire when sending or receiving. One or more Transfer events are fired during file transfer.

The BytesTransferred parameter shows the number of bytes transferred since the beginning of the transfer.

Text contains the portion of the file data being delivered.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note that events are not re-entrant. Performing time consuming operations within this event will prevent it from firing again in a timely manner and may impact overall performance.

Certificate Type

This is the digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

EffectiveDate
String

This is the date on which this certificate becomes valid. Before this date, it is not valid. The following example illustrates the format of an encoded date:

23-Jan-2000 15:00:00.

Encoded
String

This is the certificate (PEM/base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.

When Encoded is set, a search is initiated in the current Store for the private key of the certificate. If the key is found, Subject is updated to reflect the full subject of the selected certificate; otherwise, Subject is set to an empty string.

EncodedB
byte[]

This is the certificate (PEM/base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.

When Encoded is set, a search is initiated in the current Store for the private key of the certificate. If the key is found, Subject is updated to reflect the full subject of the selected certificate; otherwise, Subject is set to an empty string.

ExpirationDate
String

This is the date the certificate expires. After this date, the certificate will no longer be valid. The following example illustrates the format of an encoded date:

23-Jan-2001 15:00:00.

ExtendedKeyUsage
String

This is a comma-delimited list of extended key usage identifiers. These are the same as ASN.1 object identifiers (OIDs).

Fingerprint
String

This is the hex-encoded, 16-byte MD5 fingerprint of the certificate.

The following example illustrates the format: bc:2a:72:af:fe:58:17:43:7a:5f:ba:5a:7c:90:f7:02

FingerprintSHA1

XMPPUserInfo Type

A named registration field.

Remarks

This type describes the user information that must be sent to the server during registration.

Fields

Field
String

This is the name of the current field necessary for registration.

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the UserInfo collection accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

instructionsSpecial instructions sent from the server.
usernameThe username to be associated with this account.
passwordThe initial password for this account.
nameThe user's name.
emailThe user's email address.
addressThe user's physical address.
cityThe user's city of residence.
stateThe user's state (for United States citizens).
zipThe user's postal code (for United States citizens).
phoneThe user's phone number.
URLThe user's website.
dateThe date of registration.
miscAny miscellaneous data.
textAny extra text (potentially for a personal bio).
removeSpecifies a request to unregister.

After the user has set all of the values in UserInfo, and added any extra fields they may wish to include in their registration, the application should make a call to Register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

Value
String

This is the value for the current registration field, and should be set after calling QueryRegister and before calling Register.

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the UserInfo collection accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

instructionsSpecial instructions sent from the server.

Configuration Settings (Xmpp Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

XMPP Configuration Settings

AccessToken:   The OAuth access token used for authentication.

Specifies the OAuth access token used during authentication. This can be used when connecting to Facebook or Windows Live Messenger.

BlockSize:   Specifies the block size for file transfers.

The size in bytes of the block size used when sending files. The default value is 4096. Increasing this value may improve performance. However, some servers may not support larger block sizes.

ClientId:   The OAuth client Id used for authentication.

Specifies the OAuth client Id used during authentication. This can be used when connecting to Facebook. Windows Live Messenger does not require this value.

MessageXML:   Returns the last root-level element received by the component.

This returns the last root-level element received by the component. This could be a message, iq, presence, or any other element type.

Overwrite:   Specifies whether or not to overwrite received files.

The default value is false. If set to true, the class will overwrite the existing files in LocalDirectory if another file with the same name is received. This is only applicable when receiving file transfers.

ParseHTML:   Tells XMPP whether or not to parse MessageHTML when it's set.

If ParseHTML is true, the class will take any value sent to MessageHTML, compute a plaintext version of the text, and put it into the MessageText property.

RetrieveRoster:   Whether to automatically retrieve the roster when logging in.

When this configuration setting is set to True (default), the class will automatically retrieve the roster from the server when logging in. Setting this to False will cause the class to not request the roster, which can be useful when interacting with some non-standard XMPP servers.

SendSubscriptionResponse:   Determines whether a response will be sent to a Subscription Request.

When set to true, a response will be sent to a subscription request based upon the Accept parameter value of the SubscriptionRequest event. When set to false, a response will not be sent. Therefore a response can be created and sent using SendCommand outside of the SubscriptionRequest event. The default value is true.

UseCompression:   Specified whether or not stream compression is used.

The default value is false. If set to true, the class will use stream compression when communicating with the IMServer.

IPPort Configuration Settings

CloseStreamAfterTransfer:   If true, the component will close the upload or download stream after the transfer.

This setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. In order to keep streams open after the transfer of data, set this to False. the default value is True.

ConnectionTimeout:   Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect:   Tells the class whether or not to automatically detect and use firewall system settings, if available.

This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallHost:   Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

NOTE: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallListener:   If true, the component binds to a SOCKS firewall as a server (IPPort only).

This entry is for IPPort only and does not work for other components that descend from IPPort.

If this entry is set, the class acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost, and it is recommended that RemoteHost be set to empty string in this case.

RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.

The connection to the firewall is made by calling the Connect method.

FirewallPassword:   Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class throws an exception.

NOTE: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPort:   The TCP port for the FirewallHost;.

Note that the FirewallPort is set automatically when FirewallType is set to a valid value.

NOTE: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallType:   Determines the type of firewall to connect through.

The appropriate values are as follows:

0No firewall (default setting).
1Connect through a tunneling proxy. FirewallPort is set to 80.
2Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

NOTE: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallUser:   A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class throws an exception.

NOTE: This setting is provided for use by classs that do not directly expose Firewall properties.

KeepAliveInterval:   The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to true. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgement is received from the remote host the keep-alive packet will be re-sent. This setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime:   The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to true. By default the operating system will determine the time a connection is idle before a TCP keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger:   When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), there are two scenarios for determining how long the connection will linger. The first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP protocol timeout expires.

In the second scenario, LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data is sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action.

LingerTime:   Time in seconds to have the connection linger.

LingerTime is the time, in seconds, to leave the socket connection linger. This value is 0 by default, which means it will use the default IP protocol timeout.

LocalHost:   The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the class binds.

This must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength:   The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate:   The transfer rate limit in bytes per second.

This setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default this is not set and there is no limit.

ProxyExceptionsList:   A semicolon separated list of hosts and IPs to bypass when using a proxy.

This setting optionally specifies a semicolon separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive:   Determines whether or not the keep alive socket option is enabled.

If set to true, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay:   Whether or not to delay when sending packets.

When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config is set to false.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:

0 IPv4 Only
1 IPv6 Only
2 IPv6 with IPv4 fallback

UseNTLMv2:   Whether to use NTLM V2.

When authenticating with NTLM this setting specifies whether NTLM V2 is used. By default this value is False and NTLM V1 will be used. Set this to True to use NTLM V2.

SSL Configuration Settings

LogSSLPackets:   Controls whether SSL packets are logged when using the internal security API.

When the UseInternalSecurityAPI configuration setting is True, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this setting has no effect if UseInternalSecurityAPI is False.

ReuseSSLSession:   Determines if the SSL session is reused.

If set to true, the class will reuse the context if and only if the following criteria are met:

  • The target host name is the same.
  • The system cache entry has not expired (default timeout is 10 hours).
  • The application process that calls the function is the same.
  • The logon session is the same.
  • The instance of the class is the same.

SSLCACerts:   A newline separated list of CA certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----

..
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCheckCRL:   Whether to check the Certificate Revocation List for the server certificate.

This setting specifies whether the class will check the Certificate Revocation List specified by the server certificate. If set to true the class will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class throws an exception.

When set to false (default) the CRL check will not be performed by the class.

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.

SSLContextProtocol:   The protocol used when getting an SSLContext instance.

Possible values are SSL, SSLv2, SSLv3, TLS and TLSv1. Use it only in case your security provider does not support TLS. This is the parameter "protocol" inside the SSLContext.getInstance(protocol) call.

SSLEnabledCipherSuites:   The cipher suite to be used in an SSL negotiation.

The enabled cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Note: This value must be set after UseInternalSecurityAPI is set.

Example values: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA"); obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA; SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA"); Possible values when UseInternalSecurityAPI is False (default) include:

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:

  • TLS_AES_256_GCM_SHA384
  • TLS_CHACHA20_POLY1305_SHA256
  • TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols:   Used to enable/disable the supported security protocols.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default)
TLS1.1768 (Hex 300) (Default)
TLS1 192 (Hex C0) (Default)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList setting.

Note: TLS 1.1 and TLS1.2 support are only available starting with Windows 7.

Note: Enabling TLS 1.3 will automatically set UseInternalSecurityAPI to True.

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

This setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is true by default, but can be set to false to disable the extension.

This setting is only applicable when UseInternalSecurityAPI is set to true.

SSLIncludeCertChain:   Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

Note: When UseInternalSecurityAPI is set to True this value is automatically set to True. This is needed for proper validation when using the internal provider.

SSLKeyLogFile:   The location of a file where per-session secrets are written for debugging purposes.

This setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the class will only append, it will not overwrite previous values.

Note: This setting is only applicable when UseInternalSecurityAPI is set to True.

SSLNegotiatedCipher:   Returns the negotiated ciphersuite.

Returns the ciphersuite negotiated during the SSL handshake.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipher[connId]");

SSLNegotiatedCipherStrength:   Returns the negotiated ciphersuite strength.

Returns the strength of the ciphersuite negotiated during the SSL handshake.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite:   Returns the negotiated ciphersuite.

Returns the ciphersuite negotiated during the SSL handshake represented as a single string.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherSuite[connId]");

SSLNegotiatedKeyExchange:   Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchange[connId]");

SSLNegotiatedKeyExchangeStrength:   Returns the negotiated key exchange algorithm strength.

Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchangeStrength[connId]");

SSLNegotiatedProtocol:   Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedProtocol[connId]");

SSLProvider:   The name of the security provider to use.

Change this setting to use security providers other than the system default.

Use this setting with caution. Disabling SSL security or pointing to the wrong provider could potentially cause serious security vulnerabilities in your application.

The special value "*" (default) picks the default SSL provider defined in the system.

The special value "Internal" picks the internal SSL implementation. This does not rely on any system libraries. This is equivalent to setting UseInternalSecurityAPI to True.

Note: On Windows systems, the default SSL Provider is "Microsoft Unified Security Protocol Provider" and cannot be changed except to a value of "Internal".

SSLServerCACerts:   A newline separated list of CA certificate to use during SSL server certificate validation.

This setting optionally specifies one or more CA certificates to be used when verifying the server certificate. When verifying the server's certificate the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This setting should only be set if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

..
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLTrustManagerFactoryAlgorithm:   The algorithm to be used to create a TrustManager through TrustManagerFactory.

Possible values include SunX509. This is the parameter "algorithm" inside the TrustManagerFactory.getInstance(algorithm) call.

TLS12SignatureAlgorithms:   Defines the allowed TLS 1.2 signature algorithms when UseInternalSecurityAPI is True.

This setting specifies the allowed server certificate signature algorithms when UseInternalSecurityAPI is True and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the class will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the class throws an exception.

The format of this value is a comma separated list of hash-signature combinations. For instance: IPPort.Config("UseInternalSecurityAPI=true"); IPPort.Config("SSLEnabledProtocols=3072"); //TLS 1.2 IPPort.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups:   The supported groups for ECC.

This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and UseInternalSecurityAPI is set to True, the values refer to the supported groups for ECC. The following values are supported:

  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)

TLS13KeyShareGroups:   The groups for which to pregenerate key shares.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional round trip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.

In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448"
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1"
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096"
  • "ffdhe_6144"
  • "ffdhe_8192"

TLS13Provider:   The TLS 1.3 implementation to be used.

This setting specifies the TLS 1.3 implementation which will be used when TLS 1.3 is enabled via SSLEnabledProtocols. Possible values are:

  • 0 (Internal - Default)
  • 1 (Platform)

The platform provider is only supported on Windows 11 / Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to 1 (Platform provider) please be aware of the following notes:

  • The platform provider is only available on Windows 11 / Windows Server 2022 and up.
  • SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
  • If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2 the above restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

TLS13SignatureAlgorithms:   The allowed certificate signature algorithms.

This setting holds a comma separated list of allowed signature algorithms. Possible values are:

  • "ed25519" (default)
  • "ed448" (default)
  • "ecdsa_secp256r1_sha256" (default)
  • "ecdsa_secp384r1_sha384" (default)
  • "ecdsa_secp521r1_sha512" (default)
  • "rsa_pkcs1_sha256" (default)
  • "rsa_pkcs1_sha384" (default)
  • "rsa_pkcs1_sha512" (default)
  • "rsa_pss_sha256" (default)
  • "rsa_pss_sha384" (default)
  • "rsa_pss_sha512" (default)
The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This setting is only applicable when SSLEnabledProtocols includes TLS 1.3.
TLS13SupportedGroups:   The supported groups for (EC)DHE key exchange.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. This setting should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448" (default)
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096" (default)
  • "ffdhe_6144" (default)
  • "ffdhe_8192" (default)

Socket Configuration Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for UDP ports.

FirewallData:   Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Configuration Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable:   Tells the class whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The class will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the class does not attempt to process external events.

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
UseDaemonThreads:   Whether threads created by the class are daemon threads.

If set to True (default), when the class creates a thread, the thread's Daemon property will be explicitly set to True. When set to False, the class will not set the Daemon property on the created thread. The default value is True.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

By default the class will use the system security libraries to perform cryptographic functions. Setting this to True tells the class to use the internal implementation instead of using the system's security API.
