XMPP Module

Properties   Methods   Events   Config Settings   Errors  

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

Syntax

IPWorks.XMPP

Remarks

The XMPP class supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over Secure Sockets Layer/Transport Layer Security (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 through the Config method.

A call to the ConnectTo method will perform the entire logon process after which a Connected event will fire to indicate the 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 1. Connecting and Sending a Message:

IMControl.ConnectTo("myusername", "mypassword") IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser") Example 2. Sending a Single Message:

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

• Objective-C

public var authDomain: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=authDomain,setter=setAuthDomain:) NSString* authDomain;

- (NSString*)authDomain;
- (void)setAuthDomain :(NSString*)newAuthDomain;

Default Value

""

Remarks

Set this value if the user must authenticate through a third-party authentication service that requires a different domain than the XMPP user's registered domain.

AuthMethods Property (XMPP Module)

This property controls how the module authenticates itself with the XMPP server.

Syntax

• Swift

LocalDirectory Property (XMPP Module)

This property includes the directory to which received files are saved.

Syntax

• Swift
• Objective-C

public var localDirectory: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=localDirectory,setter=setLocalDirectory:) NSString* localDirectory;

- (NSString*)localDirectory;
- (void)setLocalDirectory :(NSString*)newLocalDirectory;

Default Value

""

Remarks

This property 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 Module)

This property includes the path to the file that will be sent.

Syntax

• Swift
• Objective-C

public var localFile: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=localFile,setter=setLocalFile:) NSString* localFile;

- (NSString*)localFile;
- (void)setLocalFile :(NSString*)newLocalFile;

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 Module)

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

Syntax

• Swift
• Objective-C

public var localHost: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=localHost,setter=setLocalHost:) NSString* localHost;

- (NSString*)localHost;
- (void)setLocalHost :(NSString*)newLocalHost;

Default Value

""

Remarks

This 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 multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

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 multihomed 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 Module)

This property includes the HTML version of the current message.

Syntax

• Swift
• Objective-C

public var messageHTML: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=messageHTML,setter=setMessageHTML:) NSString* messageHTML;

- (NSString*)messageHTML;
- (void)setMessageHTML :(NSString*)newMessageHTML;

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.

MessageThread Property (XMPP Module)

This property is the thread name of the current message.

Syntax

• Swift
• Objective-C

public var messageThread: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=messageThread,setter=setMessageThread:) NSString* messageThread;

- (NSString*)messageThread;
- (void)setMessageThread :(NSString*)newMessageThread;

MessageType Property (XMPP Module)

This property is the type of the current message.

Syntax

• Swift
• Objective-C

public var messageType: XMPPMessageTypes {
  get {...}
  set {...}
}

public enum XMPPMessageTypes: Int32 {
  case jmtNormal = 0
  case jmtChat = 1

- (int)messageType;
- (void)setMessageType :(int)newMessageType;

Default Value

0

Remarks

MessageType is the type of the message as specified in the XMPP RFC. The possible values are defined in the protocol specification as follows:

Password Property (XMPP Module)

This property is the user's password.

Syntax

• Swift
• Objective-C

public var password: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=password,setter=setPassword:) NSString* password;

- (NSString*)password;
- (void)setPassword :(NSString*)newPassword;

Default Value

""

Remarks

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

Presence Property (XMPP Module)

This property indicates the availability of the entity.

Syntax

• Swift
• Objective-C

public var presence: XMPPPresences {
  get {...}
}

public enum XMPPPresences: Int32 {
  case pcOffline = 0
  case pcChat = 1
  case pcAway = 2
  case pcXA = 3
  case pcDND = 4
}

@property (nonatomic,readonly,assign,getter=presence) int presence;

- (int)presence;

Default Value

1

Remarks

When the class completes the initial login, it will send information telling other entities subscribed to this entity's presence that it is online.

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

By default, the class sets the client presence to pcChat, meaning that the user is available.

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, "".

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.

This property is read-only.

Resource Property (XMPP Module)

This property is the resource for the current session.

Syntax

• Swift
• Objective-C

public var resource: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=resource,setter=setResource:) NSString* resource;

- (NSString*)resource;
- (void)setResource :(NSString*)newResource;

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 Module)

This property includes the XMPP server's domain.

Syntax

• Swift
• Objective-C

public var serverDomain: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=serverDomain,setter=setServerDomain:) NSString* serverDomain;

- (NSString*)serverDomain;
- (void)setServerDomain :(NSString*)newServerDomain;

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.

- (NSData*)SSLAcceptServerCertEncodedB;
- (void)setSSLAcceptServerCertEncodedB :(NSData*)newSSLAcceptServerCertEncoded;
 

Default Value

""

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.

Note: This functionality is provided only for cases in which 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.

- (void)setSSLEnabled :(BOOL)newSSLEnabled;

Default Value

False

Remarks

This property 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.

SSLProvider Property (XMPP Module)

The Secure Sockets Layer/Transport Layer Security (SSL/TLS) implementation to use.

Syntax

• Swift
• Objective-C

public var sslProvider: XMPPSSLProviders {
  get {...}

  case sslpInternal = 2
}

@property (nonatomic,readwrite,assign,getter=SSLProvider,setter=setSSLProvider:) int SSLProvider;

- (int)SSLProvider;
- (void)setSSLProvider :(int)newSSLProvider;

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic), the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are as follows:

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, the platform implementation will be used by default in all cases in the macOS edition.

SSLStartMode Property (XMPP Module)

This property determines how the module starts the Secure Sockets Layer (SSL) negotiation.

Syntax

• Swift
• Objective-C

public var sslStartMode: XMPPSSLStartModes {
  get {...}
  set {...}
}

public enum XMPPSSLStartModes: Int32 {
  case sslAutomatic = 0
  case sslImplicit = 1
  case sslExplicit = 2
  case sslNone = 3
}

@property (nonatomic,readwrite,assign,getter=SSLStartMode,setter=setSSLStartMode:) int SSLStartMode;

- (int)SSLStartMode;
- (void)setSSLStartMode :(int)newSSLStartMode;

Default Value

3

Remarks

The SSLStartMode property may have one of the following values:

Status Property (XMPP Module)

This property holds the description of the availability of this entity.

Syntax

• Swift
• Objective-C

public var status: String {
  get {...}
}

@property (nonatomic,readonly,assign,getter=status) NSString* status;

- (NSString*)status;

Default Value

"Available for Chat."

Remarks

When the class completes the initial login, it will send information telling other entities subscribed to this entity's presence that it is online.

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

By default, the class sets the client presence to pcChat, meaning that the user is available.

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, "".

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.

This property is read-only.

Timeout Property (XMPP Module)

The timeout for the module.

Syntax

• Swift
• Objective-C

public var timeout: Int32 {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=timeout,setter=setTimeout:) int timeout;

- (int)timeout;
- (void)setTimeout :(int)newTimeout;

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 .

Note: By default, all timeouts are inactivity timeouts, that is, 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 Module)

This property includes the user portion of this entity's Jabber Id.

Syntax

• Swift
• Objective-C

public var user: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=user,setter=setUser:) NSString* user;

- (NSString*)user;
- (void)setUser :(NSString*)newUser;

Default Value

""

Remarks

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

UserDomain Property (XMPP Module)

This property gets or sets the domain value used for Jabber Ids.

Syntax

• Swift
• Objective-C

public var userDomain: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=userDomain,setter=setUserDomain:) NSString* userDomain;

- (NSString*)userDomain;
- (void)setUserDomain :(NSString*)newUserDomain;

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 log in.

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

UserInfo Property (XMPP Module)

This property includes the collection of named registration fields.

Syntax

• Swift
• Objective-C

public var userInfo: [String: XMPPUserInfo] {
  get {...}
}

@property (nonatomic,readwrite,assign,getter=userInfoCount,setter=setUserInfoCount:) int userInfoCount;

- (int)userInfoCount;
- (void)setUserInfoCount :(int)newUserInfoCount;

- (NSString*)userInfoField:(int)fieldIndex;
- (void)setUserInfoField:(int)fieldIndex :(NSString*)newUserInfoField;

- (NSString*)userInfoValue:(int)fieldIndex;
- (void)setUserInfoValue:(int)fieldIndex :(NSString*)newUserInfoValue;

Default Value

""

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 properties 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:

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 hash-table type of collection in which the field string is used as the key to the desired XMPP user info object.

Example. Setting New User Information:

xmpp1.QueryRegister("server"); xmpp1.UserInfoCount = 2 xmpp1.UserInfoField(0) = "Username" xmpp1.UserInfoValue(0) = "newuser" xmpp1.UserInfoField(1) = "Password" xmpp1.UserInfoValue(1) = "newpass" xmpp1.Register("server");

Add Method (XMPP Module)

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

Syntax

• Swift
• Objective-C

public func add(jabberId: String, name: String, groups: String) throws -> Void

- (void)add:(NSString*)jabberId :(NSString*)name :(NSString*)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 the 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 Module)

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

Syntax

• Swift
• Objective-C

public func cancel(jabberId: String) throws -> Void

- (void)cancel:(NSString*)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 Module)

This method will change the current user's password.

Syntax

• Swift
• Objective-C

public func changePassword(password: String) throws -> Void

- (void)changePassword:(NSString*)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 Module)

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

Syntax

• Swift
• Objective-C

public func changePresence(presenceCode: Int32, status: String) throws -> Void

- (void)changePresence:(int)presenceCode :(NSString*)status;

Remarks

PresenceCode should correspond to the possible values of the Presence property:

By default, the class sets the client presence to pcChat, meaning that the user is available.

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 Module)

Sets or retrieves a configuration setting.

Syntax

• Swift
• Objective-C

public func config(configurationString: String) throws -> String

- (NSString*)config:(NSString*)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 Module)

This method will connect the component to the server.

Syntax

• Swift
• Objective-C

public func connect() throws -> Void

- (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 Transmission Control Protocol (TCP) connection and again when the XMPP Logon is complete.

ConnectTo Method (XMPP Module)

This method will connect the component to the server.

Syntax

• Swift
• Objective-C

public func connectTo(user: String, password: String) throws -> Void

- (void)connectTo:(NSString*)user :(NSString*)password;

Remarks

The ConnectTo 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 Transmission Control Protocol (TCP) connection and again when the XMPP Logon is complete.

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

Disconnect Method (XMPP Module)

This method disconnects the component from the server.

Syntax

• Swift
• Objective-C

public func disconnect() throws -> Void

- (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 Module)

This method processes events from the internal message queue.

Syntax

• Swift
• Objective-C

public func doEvents() throws -> Void

- (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 Module)

This method interrupts the current method.

Syntax

• Swift
• Objective-C

public func interrupt() throws -> Void

- (void)interrupt;

Remarks

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

ProbePresence Method (XMPP Module)

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

Syntax

• Swift
• Objective-C

public func probePresence(jabberId: String) throws -> Void

- (void)probePresence:(NSString*)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 Module)

This method queries a server for the necessary registration fields.

Syntax

• Swift
• Objective-C

public func queryRegister(xmppServer: String) throws -> Void

- (void)queryRegister:(NSString*)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 properties 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:

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 Module)

This method registers an account with a server.

Syntax

• Swift
• Objective-C

public func registerUser(xmppServer: String) throws -> Void

- (void)register:(NSString*)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 properties 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:

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 Module)

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

Syntax

• Swift
• Objective-C

public func remove(jabberId: String, name: String, group: String) throws -> Void

- (void)remove:(NSString*)jabberId :(NSString*)name :(NSString*)group;

Remarks

JabberId is the Jabber Id of the entity to be removed. It should be in the form of "user@host". If no hostname is specified, the class will assume the user's account is with the server in IMServer, and it 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 a subscription of type subscriptionRemove, and the entry will be removed from the Jabber class's internally stored list.

Reset Method (XMPP Module)

This method will reset the component.

Syntax

• Swift
• Objective-C

public func reset() throws -> Void

- (void)reset;

Remarks

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

RetrieveRoster Method (XMPP Module)

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

Syntax

• Swift
• Objective-C

public func retrieveRoster() throws -> Void

- (void)retrieveRoster;

Remarks

After the class connects, it will automatically send a request to the server to retrieve the roster. If, however, 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 Module)

This method sends a command to the server.

Syntax

• Swift
• Objective-C

public func sendCommand(command: String) throws -> Void

- (void)sendCommand:(NSString*)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 be used only by programmers or users who are connecting to nonstandard 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 nonstandard IQ message will be returned by the IQ event. All other responses will be returned by the PITrail event.

SendFile Method (XMPP Module)

This method sends a file to the specified user.

Syntax

• Swift
• Objective-C

public func sendFile(jabberId: String) throws -> Void

- (void)sendFile:(NSString*)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.

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

SendMessage Method (XMPP Module)

This method will send a message to the specified user.

Syntax

• Swift
• Objective-C

public func sendMessage(jabberId: String) throws -> String

- (NSString*)sendMessage:(NSString*)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 (i.e., 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 nonempty string values ("") and will clear all properties after a successful send.

The associated properties are the following:

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 subdomains.

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.

SetUserInfoField Method (XMPP Module)

This method will add a user information field for registration.

Syntax

• Swift
• Objective-C

public func setUserInfo(field: String, value: String) throws -> Void

- (void)setUserInfoField:(NSString*)field :(NSString*)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 be 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 properties 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:

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 Module)

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

Syntax

• Swift
• Objective-C

public func subscribeTo(jabberId: String) throws -> Void

- (void)subscribeTo:(NSString*)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 Module)

This method cancels an account with the host.

Syntax

• Swift
• Objective-C

public func unregister() throws -> Void

- (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 Module)

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

Syntax

• Swift
• Objective-C

public func unsubscribeTo(jabberId: String) throws -> Void

- (void)unsubscribeTo:(NSString*)jabberId;

Remarks

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

UpdateBuddyGroup Method (XMPP Module)

This method updates the buddy's associated groups.

Syntax

• Swift
• Objective-C

public func updateBuddyGroup(buddyIndex: Int32, group: String) throws -> Void

- (void)updateBuddyGroup:(int)buddyIndex :(NSString*)group;

Remarks

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

After the Sync event has fired, the BuddiesGroup property 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-separated list of groups the buddy should be associated with. Setting Group to an empty string ("") will cause the buddy to be completely disassociated from all groups.

BuddyUpdate Event (XMPP Module)

This event is fired whenever a roster entry is updated.

Syntax

• Swift
• Objective-C

func onBuddyUpdate(buddyIdx: Int32)

- (void)onBuddyUpdate:(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 properties property. The BuddyIdx parameter of this event will be the index of that XMPPBuddy in the properties.

Connected Event (XMPP Module)

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

Syntax

• Swift
• Objective-C

func onConnected(statusCode: Int32, description: String)

- (void)onConnected:(int)statusCode :(NSString*)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 Transmission Control Protocol (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.

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 Module)

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

Syntax

• Swift
• Objective-C

func onError(errorCode: Int32, description: String)

- (void)onError:(int)errorCode :(NSString*)description;

Remarks

This event 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 Module)

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

Syntax

• Swift
• Objective-C

func onIQ(iq: String, id: String, from: String, iqType: String, ignore: inout Bool)

- (void)onIQ:(NSString*)iq :(NSString*)id :(NSString*)from :(NSString*)iqType :(int*)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 it 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:

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

MessageIn Event (XMPP Module)

This event is fired upon receipt of a message.

Syntax

• Swift
• Objective-C

func onMessageIn(messageId: String, from: String, domain: String, resource: String, messageType: Int32, subject: String, messageThread: String, messageText: String, messageHTML: String, other: String)

- (void)onMessageIn:(NSString*)messageId :(NSString*)from :(NSString*)domain :(NSString*)resource :(int)messageType :(NSString*)subject :(NSString*)messageThread :(NSString*)messageText :(NSString*)messageHTML :(NSString*)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 is the type of message received. See MessageType for a list of possible values. For a message of type "headline", Subject will reflect the subject of the message. For a message of type "chat", Thread will report the conversation thread for which the current message is a follow-up.

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

PITrail Event (XMPP Module)

This event is fired for all protocol messages.

Syntax

• Swift
• Objective-C

func onPITrail(direction: Int32, pi: String)

- (void)onPITrail:(int)direction :(NSString*)pi;

Remarks

The PITrail event is useful for debugging purposes. It shows all the interactions 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:

The Pi parameter contains the PI message.

Presence Event (XMPP Module)

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

Syntax

• Swift
• Objective-C

func onPresence(user: String, domain: String, resource: String, availability: Int32, status: String)

- (void)onPresence:(NSString*)user :(NSString*)domain :(NSString*)resource :(int)availability :(NSString*)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:

By default, the class sets the client presence to pcChat, meaning that the user is available.

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 Module)

This event is fired when the component is ready to send data.

Syntax

• Swift
• Objective-C

func onReadyToSend()

- (void)onReadyToSend;

Remarks

The ReadyToSend event indicates that the underlying Transmission Control Protocol (TCP)/IP subsystem is ready to accept data after a failed SendBytes. This event also is fired immediately after a connection to the remote host is established.

SSLServerAuthentication Event (XMPP Module)

Fired after the server presents its certificate to the client.

Syntax

• Swift
• Objective-C

func onSSLServerAuthentication(certEncoded: Data, certSubject: String, certIssuer: String, status: String, accept: inout Bool)

- (void)onSSLServerAuthentication:(NSData*)certEncoded :(NSString*)certSubject :(NSString*)certIssuer :(NSString*)status :(int*)accept;

Remarks

During this event, the client can decide whether or not to continue with the connection process. 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 or not to continue.

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 Module)

Fired when secure connection progress messages are available.

Syntax

• Swift
• Objective-C

func onSSLStatus(message: String)

- (void)onSSLStatus:(NSString*)message;

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (XMPP Module)

This event is fired when a file transfer begins.

Syntax

• Swift
• Objective-C

func onStartTransfer(direction: Int32, fileId: String, user: String, domain: String, resource: String, fileName: inout String, datetime: String, size: Int64, accept: inout Bool)

- (void)onStartTransfer:(int)direction :(NSString*)fileId :(NSString*)user :(NSString*)domain :(NSString*)resource :(NSString**)fileName :(NSString*)datetime :(long long)size :(int*)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.

When 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 Module)

This event fires when a subscription request is received.

Syntax

• Swift
• Objective-C

func onSubscriptionRequest(from: String, domain: String, accept: inout Bool)

- (void)onSubscriptionRequest:(NSString*)from :(NSString*)domain :(int*)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. It is not necessary to know which resource sent the request, because 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 Module)

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

Syntax

• Swift
• Objective-C

func onSync()

- (void)onSync;

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 properties will be filled out accordingly:

Note: Please refer to Buddies properties property for more information.

Transfer Event (XMPP Module)

This event is fired during file transfer.

Syntax

• Swift
• Objective-C

func onTransfer(direction: Int32, fileId: String, fileName: String, bytesTransferred: Int64, percentDone: Int32, text: Data, cancel: inout Bool)

- (void)onTransfer:(int)direction :(NSString*)fileId :(NSString*)fileName :(long long)bytesTransferred :(int)percentDone :(NSData*)text :(int*)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 cannot 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: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
