Remarks

The STOMP class provides an easy-to-use STOMP client implementation that supports STOMP versions 1.1 and 1.2. The class supports both plaintext and TLS-enabled connections over TCP.

Connecting

Connecting to a STOMP server is easy; in the simplest case just call the ConnectTo method, passing the server's hostname and port number.

When connecting to a STOMP server, the class sends information from the following properties, if populated:

• IncomingHeartbeat
• OutgoingHeartbeat
• User
• Password

In addition to the above properties, the following configuration settings can be set before connecting (though in most cases this is not necessary):

• SupportedVersions: Controls which STOMP versions the class advertises support for.
• VirtualHost: Controls the virtual host to connect to. If left empty (default), the value from RemoteHost is used.

Subscriptions & Receiving Messages

When Subscribe is called, it will return a subscription Id. To unsubscribe, pass this subscription Id to the Unsubscribe method.

After subscribing to a message destination, any messages received will cause the MessageIn event to fire.

Basic Subscriptions Example stomp1.OnMessageIn += (s, e) => { Console.WriteLine("Received message from destination '" + e.Destination + "':"); Console.WriteLine(e.Data); }; string subId = stomp1.Subscribe("test/a/b", false); // Some time later... stomp1.Unsubscribe(subId);

Refer to Subscribe, Unsubscribe, and MessageIn for more information about subscriptions and receiving messages.

Sending Messages

To send messages, use the SendMessage and SendData methods. SendMessage is used to send messages with string payloads, while SendData is used to send messages with binary payloads.

Send String Message Example stomp1.SendMessage("test/a/b", "Hello, world!");

Send Binary Message Example byte[] fileContent = File.ReadAllBytes("C:\test\stuff.dat"); stomp1.SendData("test/a/b", fileContent);

Refer to SendMessage and SendData for more information about sending messages.

Using Transactions

STOMP transactions are used to group messages together for processing on the server. Messages sent as part of a transaction will not be delivered by the server until the transaction is committed. If the transaction is aborted, the server will discard the messages without attempting to deliver them.

Basic Transaction Example // Open a new transaction. stomp1.BeginTransaction("txn1"); // Set the Transaction property to make sure that messages are sent as part of the transaction. stomp1.Transaction = "txn1"; stomp1.SendMessage("test/a/b", "Hello, world!"); stomp1.SendMessage("test/a/b", "This is a test."); stomp1.SendMessage("test/a/b", "Another test!"); // At this point, none of the messages sent above would have been delivered to any clients // subscribed to the "test/a/b" destination yet, because the transaction is still open. // If we close and commit the transaction, the server will then deliver the messages to subscribers, // queue them, or process them in another manner; the behavior is server-dependent. stomp1.CommitTransaction("txn1"); // Or, the transaction can be aborted, in which case the server will discard the messages // without delivering them to the subscribers. //stomp1.AbortTransaction("txn1"); // Reset (or change) the Transaction property after committing or aborting a transaction // so that future messages are not associated with the previous transaction. stomp1.Transaction = "";

Refer to BeginTransaction for more information about using transactions.

Connected Property (IPWorksMQ_STOMP Class)

Triggers a connection or disconnection.

Object Oriented Interface

public function getConnected();
public function setConnected($value);

Procedural Interface

ipworksmq_stomp_get($res, 1 );
ipworksmq_stomp_set($res, 1, $value );

Default Value

false

Remarks

This property triggers a connection or disconnection. Setting this property to True makes the class attempt to connect to the host identified by the RemoteHost property. If successful, after the connection is achieved the value of the property changes to True and the Connected event is fired.

Setting this property to False closes the connection.

When connecting to a STOMP server, the class sends information from the following properties, if populated:

• IncomingHeartbeat
• OutgoingHeartbeat
• User
• Password

In addition to the above properties, the following configuration settings can be set before connecting (though in most cases this is not necessary):

• SupportedVersions: Controls which STOMP versions the class advertises support for.
• VirtualHost: Controls the virtual host to connect to. If left empty (default), the value from RemoteHost is used.

This property is not available at design time.

Data Type

Boolean

ContentType Property (IPWorksMQ_STOMP Class)

The content type of the outgoing message.

Object Oriented Interface

public function getContentType();
public function setContentType($value);

Procedural Interface

ipworksmq_stomp_get($res, 2 );
ipworksmq_stomp_set($res, 2, $value );

Default Value

'text/plain'

Remarks

This property is used to specify the content type (MIME type) for outgoing messages sent using SendMessage. The default value is text/plain, which should be sufficient is most cases.

Note that this property is ignored for messages sent using SendData, as such messages do not have a content-type header added to them. The absence of a content-type header indicates to the server that the data should be treated as a binary blob.

This property is not available at design time.

Data Type

String

Data Type

String

IncomingHeartbeat Property (IPWorksMQ_STOMP Class)

Specifies the server-to-class heartbeat timing.

Object Oriented Interface

public function getIncomingHeartbeat();
public function setIncomingHeartbeat($value);

Procedural Interface

ipworksmq_stomp_get($res, 12 );
ipworksmq_stomp_set($res, 12, $value );

Default Value

0

Remarks

This property specifies the incoming heartbeat interval, which is the number of seconds without any server-to-class communication that the server will allow to elapse before sending the class a heartbeat (keepalive). If set to 0 (default), incoming heartbeats are disabled.

For information about outgoing (class-to-server) heartbeats; see the OutgoingHeartbeat property.

Before Connecting

Before connecting, this property is used to specify the desired incoming heartbeat interval (in seconds). By default, this property is set to 0 (no heartbeat).

During the connection process, the incoming heartbeat interval requested by the class is compared to the minimum interval supported by the server, and the larger of the two values is selected. If one or both sides supply 0 as their value, then no server-to-class heartbeats will be sent.

After Connecting

After connecting, this property cannot be set. Instead, it reflects the incoming heartbeat interval agreed upon by the class and the server during the connection process.

As the incoming heartbeat interval negotiation notes above imply, it is possible that the agreed-upon incoming heartbeat interval may either be larger than what the class requested, or may be 0 (i.e., incoming heartbeats are disabled).

This property is not available at design time.

Data Type

Integer

LocalHost Property (IPWorksMQ_STOMP Class)

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

Object Oriented Interface

public function getLocalHost();
public function setLocalHost($value);

Procedural Interface

ipworksmq_stomp_get($res, 13 );
ipworksmq_stomp_set($res, 13, $value );

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.

Data Type

String

LocalPort Property (IPWorksMQ_STOMP Class)

The TCP port in the local host where the class binds.

Object Oriented Interface

public function getLocalPort();
public function setLocalPort($value);

Procedural Interface

ipworksmq_stomp_get($res, 14 );
ipworksmq_stomp_set($res, 14, $value );

Default Value

0

Remarks

This property 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 property to 0 (default) enables the system to choose an open port at random. The chosen port will be returned by the LocalPort property after the connection is established.

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

This property is useful when trying to connect to services that require a trusted port on the client side.

Data Type

Integer

OutgoingHeartbeat Property (IPWorksMQ_STOMP Class)

Specifies the class-to-server heartbeat timing.

Object Oriented Interface

public function getOutgoingHeartbeat();
public function setOutgoingHeartbeat($value);

Procedural Interface

ipworksmq_stomp_get($res, 15 );
ipworksmq_stomp_set($res, 15, $value );

Default Value

0

Remarks

This property specifies the outgoing heartbeat interval, which is the number of seconds without any class-to-server communication that the class will allow to elapse before sending the server a heartbeat (keepalive). If set to 0 (default), outgoing heartbeats are disabled.

For information about incoming (server-to-class) heartbeats; see the IncomingHeartbeat property.

Before Connecting

Before connecting, this property is used to specify the minimum supported outgoing heartbeat interval (in seconds). By default, this property is set to 0 (no heartbeat).

During the connection process, the minimum outgoing heartbeat interval supported by the class is compared to the interval requested by the server, and the larger of the two values is selected. If one or both sides supply 0 as their value, then no class-to-server heartbeats will be sent.

After Connecting

After connecting, this property cannot be set. Instead, it reflects the outgoing heartbeat interval agreed upon by the class and the server during the connection process.

As the outgoing heartbeat interval negotiation notes above imply, it is possible that the agreed-upon outgoing heartbeat interval may either be larger than the class's supported minimum, or may be 0 (i.e., outgoing heartbeats are disabled).

This property is not available at design time.

String

ReadyToSend Property (IPWorksMQ_STOMP Class)

Indicates whether the class is ready to send data.

Object Oriented Interface

public function getReadyToSend();

Procedural Interface

ipworksmq_stomp_get($res, 20 );

Default Value

false

Remarks

This property indicates that the underlying TCP/IP subsystem is ready to accept data. This is True after connecting to the remote host, and will become False if a call to SendData or SendMessage fails due to a WOULDBLOCK condition.

Once data can be sent again, the ReadyToSend event will fire and this property will be True.

If a WOULDBLOCK error occurs while sending a message the class will automatically complete the transmission when sending is possible. No action needs to be taken to re-send the message. ReadyToSend will fire after the class completes any partially sent messages.

This property is read-only and not available at design time.

Data Type

Boolean

RemoteHost Property (IPWorksMQ_STOMP Class)

The address of the remote host. Domain names are resolved to IP addresses.

Object Oriented Interface

public function getRemoteHost();
public function setRemoteHost($value);

Procedural Interface

ipworksmq_stomp_get($res, 21 );
ipworksmq_stomp_set($res, 21, $value );

Default Value

''

Remarks

This property specifies the IP address (IP number in dotted internet format) or Domain Name of the remote host. It is set before a connection is attempted and cannot be changed once a connection is established.

If this property is set to a Domain Name, a DNS request is initiated, and upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned.

If the class is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution.

By default the class will connect in plaintext. To enable SSL set SSLEnabled to True.

Data Type

String

RemotePort Property (IPWorksMQ_STOMP Class)

The port of the STOMP server (default is 61613). The default port for SSL is 61612.

Object Oriented Interface

public function getRemotePort();
public function setRemotePort($value);

Procedural Interface

ipworksmq_stomp_set($res, 22, $value );

Default Value

61613

Remarks

This property specifies a service port on the remote host to connect to.

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.

This property is not available at design time.

Data Type

Integer

RequestReceipts Property (IPWorksMQ_STOMP Class)

Whether the class should request that the server provide message receipts.

Object Oriented Interface

public function getRequestReceipts();
public function setRequestReceipts($value);

Procedural Interface

ipworksmq_stomp_get($res, 23 );
ipworksmq_stomp_set($res, 23, $value );

Default Value

false

Remarks

This property is used to specify whether the class should request that the server send back confirmations (known as a "receipts" in STOMP terminology) when it receives messages from the class. This is done by adding a receipt header to the outgoing frame.

When this property is set to True, and a message is sent, the ReceiptOut event will fire immediately after the MessageOut event fires.

Note that, while this property only controls receipt requests for outgoing messages, the class is capable of requesting receipts for any outgoing frame type. Use this table to determine which API members control receipt request for each outgoing frame type (all are False by default):

Received Receipt Notes

When a receipt is received, the ReceiptIn event fires.

Note that receipts are cumulative, and a STOMP server is not required to send back discrete receipts for each frame it receives that has a receipt header. For example, if the class has sent four message frames with the following receipt header values (in chronological order):

1. SEND-3
2. SEND-4
3. SEND-5
4. SEND-6

This property is not available at design time.

public function setTimeout($value);

Procedural Interface

ipworksmq_stomp_get($res, 110 );
ipworksmq_stomp_set($res, 110, $value );

Default Value

60

Remarks

If the Timeout property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.

If Timeout is set to a positive value, data is sent in a blocking manner and the class will wait for the operation to complete before returning control. The class will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.

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 fails with an error.

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.

Procedural Interface

ipworksmq_stomp_do_addheader($res, $key, $value);

Remarks

This method is used to add user-defined headers to the list of headers held by the Headers collection property.

When SendMessage or SendData is called, all headers in the Headers collection property are added to the outgoing message.

Note that the STOMP specification defines a number of standard headers necessary for implementing the STOMP protocol. When constructing an outgoing message, the class silently ignores any user-defined headers that are already set by the class.

BeginTransaction Method (IPWorksMQ_STOMP Class)

Begins a new transaction.

Object Oriented Interface

public function doBeginTransaction($id);

Procedural Interface

ipworksmq_stomp_do_begintransaction($res, $id);

Remarks

This method begins a new transaction using the specified Id, which must be unique. There is no limit to how many transactions may be open at any given time.

A transaction is a group of messages and message acknowledgments which are all processed atomically when the transaction is committed or aborted.

Messages sent in a transaction will not be delivered to clients subscribed to the messages' destinations until the transaction is committed.

Since it is possible for multiple transactions to be open at any given time, the TransactionId property is used to specify which transaction (if any) messages should be sent in. Similarly, message acknowledgments can be sent in a transaction by setting the AckTransactionId configuration setting during the MessageIn event handler.

The OpenTransactions configuration setting can be queried at any time to retrieve a comma-separated list of currently open transactions' Ids.

Basic Transaction Example // Open a new transaction. stomp1.BeginTransaction("txn1"); // Set the Transaction property to make sure that messages are sent as part of the transaction. stomp1.Transaction = "txn1"; stomp1.SendMessage("test/a/b", "Hello, world!"); stomp1.SendMessage("test/a/b", "This is a test."); stomp1.SendMessage("test/a/b", "Another test!"); // At this point, none of the messages sent above would have been delivered to any clients // subscribed to the "test/a/b" destination yet, because the transaction is still open. // If we close and commit the transaction, the server will then deliver the messages to subscribers, // queue them, or process them in another manner; the behavior is server-dependent. stomp1.CommitTransaction("txn1"); // Or, the transaction can be aborted, in which case the server will discard the messages // without delivering them to the subscribers. //stomp1.AbortTransaction("txn1"); // Reset (or change) the Transaction property after committing or aborting a transaction // so that future messages are not associated with the previous transaction. stomp1.Transaction = "";

CommitTransaction Method (IPWorksMQ_STOMP Class)

Commits an existing transaction.

Object Oriented Interface

public function doCommitTransaction($id);

Procedural Interface

ipworksmq_stomp_do_committransaction($res, $id);

Remarks

This method commits a transaction previously started with BeginTransaction. Id identifies the transaction to commit.

The OpenTransactions configuration setting can be queried to obtain a list of currently-open transactions.

Refer to BeginTransaction for more information about transactions.

Config Method (IPWorksMQ_STOMP Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

ipworksmq_stomp_do_config($res, $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.

Remarks

This method publishes a STOMP message with a raw data payload to the specified Destination. The MessageOut event will fire after the message has been sent.

The STOMP specification does not place any restrictions on Destination names. Instead, each STOMP server is free to define its own requirements for, and/or interpretations of, a Destination name; for example, a server might prohibit certain characters, require a specific format, or interpret some patterns in a special manner. Be sure to consult the documentation for your STOMP server to determine how to build proper Destination names.

In addition to the payload, the outgoing messages will include:

• All user-defined headers held by the Headers collection property.
• If the TransactionId property is populated, the transaction Id that it specifies (which associates the message with that transaction).

If RequestReceipts is enabled when this method is called, the class will request that the server send back a receipt to confirm it has received the message. Refer to RequestReceipts for more information.

Note that no content type is defined for raw data payload messages; so the ContentType property is ignored by this method.

Send String Message Example stomp1.SendMessage("test/a/b", "Hello, world!");

Send Binary Message Example byte[] fileContent = File.ReadAllBytes("C:\test\stuff.dat"); stomp1.SendData("test/a/b", fileContent);

Once subscribed, the Subscribed event will fire and an item will be added to the Subscriptions collection property. The MessageIn event will fire anytime a message is received for any subscription.

The STOMP specification does not place any restrictions on Destination names. Instead, each STOMP server is free to define its own requirements for, and/or interpretations of, a Destination name; for example, a server might prohibit certain characters, require a specific format, or interpret some patterns in a special manner. Be sure to consult the documentation for your STOMP server to determine how to build proper Destination names.

If the RequireAcks parameter is set to True, the server will expect the class to send it a message acknowledgment for each message it delivers as part of this subscription. (Refer to the MessageIn event for more information about sending message acknowledgments).

Basic Subscriptions Example stomp1.OnMessageIn += (s, e) => { Console.WriteLine("Received message from destination '" + e.Destination + "':"); Console.WriteLine(e.Data); }; string subId = stomp1.Subscribe("test/a/b", false); // Some time later... stomp1.Unsubscribe(subId);

Unsubscribe Method (IPWorksMQ_STOMP Class)

Removes an existing subscription.

Object Oriented Interface

public function doUnsubscribe($id);

Procedural Interface

ipworksmq_stomp_do_unsubscribe($res, $id);

Remarks

This method removes an existing subscription identified by the given Id, unsubscribing the class from the destination associated with the subscription.

Once unsubscribed, the relevant item will be removed from the Subscriptions collection property and the Unsubscribed event will fire.

Basic Subscriptions Example stomp1.OnMessageIn += (s, e) => { Console.WriteLine("Received message from destination '" + e.Destination + "':"); Console.WriteLine(e.Data); }; string subId = stomp1.Subscribe("test/a/b", false); // Some time later... stomp1.Unsubscribe(subId);

Connected Event (IPWorksMQ_STOMP Class)

Fired immediately after a connection completes (or fails).

Object Oriented Interface

public function fireConnected($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 1, array($this, 'fireConnected'));

Parameter List

 'statuscode'
 '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.

ConnectionStatus Event (IPWorksMQ_STOMP Class)

Fired to indicate changes in the connection state.

Object Oriented Interface

public function fireConnectionStatus($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 2, array($this, 'fireConnectionStatus'));

Parameter List

 'connectionevent'
 'statuscode'
 'description'

Remarks

This event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.

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

Disconnected Event (IPWorksMQ_STOMP Class)

Fired when a connection is closed.

Object Oriented Interface

public function fireDisconnected($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 3, array($this, 'fireDisconnected'));

Parameter List

 'statuscode'
 '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 Transmission Control Protocol (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.

Error Event (IPWorksMQ_STOMP Class)

Fired when a class or protocol error occurs.

Object Oriented Interface

public function fireError($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 4, array($this, 'fireError'));

Parameter List

 'errorcode'
 'description'
 'data'

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

STOMP Protocol Errors

When this occurs, ErrorCode will be 600, Description will reflect the value of the ERROR frame's message header, and Data will contain the body of the ERROR frame (if one is present).

The ErrorHeaders configuration setting will also be populated with the raw headers from the ERROR frame for the duration of the Error event handler.

Log Event (IPWorksMQ_STOMP Class)

Fired once for each log message.

Object Oriented Interface

public function fireLog($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 5, array($this, 'fireLog'));

Parameter List

 'loglevel'
 'message'
 'logtype'

Remarks

This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of the Message. Possible values are:

LogType identifies the type of log entry. Possible values are:

• Info: General information about the class.
• Acknowledgment: Information about outgoing message acknowledgments.
• Frame: Frame content logging.

MessageIn Event (IPWorksMQ_STOMP Class)

Fired when a message has been received.

Object Oriented Interface

public function fireMessageIn($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 6, array($this, 'fireMessageIn'));

Parameter List

 'messageid'
 'subscriptionid'
 'destination'
 'data'
 'contenttype'
 'ack'

Remarks

This events fires whenever the class has received a message.

In addition to the message details exposed by the event parameters, the ParsedHeaders collection property is populated with the headers parsed from the message. When the MessageIn event handler exits, the parsed headers are cleared. The following parameters are available within this event:

• MessageId: The unique Id of the message.
• SubscriptionId: The subscription Id the message is associated with.
• Destination: The message destination on the server which the message originated from.
• Data: The message's payload.
• ContentType: The content type of the message (may be empty).
• Ack: Set to True or False to control whether the class should send back a positive (True, default) or negative (False) message acknowledgment.

Message acknowledgments are only sent back to the server for messages which require them. A positive acknowledgment indicates that the message has been accepted, while a negative acknowledgment represents that the message has been rejected.

The following two configuration settings are also relevant in the context of sending back message acknowledgments for incoming messages:

• The AckTransactionId configuration setting, if not empty, specifies a transaction Id to associate the message acknowledgment with. It can only be set during the MessageIn event handler, and will be reset when the event handler ends.
• The RequestAckReceipts configuration setting controls whether the class will request that the server confirm receipt of the message acknowledgment. It is False by default, and can be set at any time.

MessageOut Event (IPWorksMQ_STOMP Class)

Fired after a message has been sent.

Object Oriented Interface

public function fireMessageOut($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 7, array($this, 'fireMessageOut'));

Parameter List

 'destination'
 'data'
 'contenttype'

Remarks

This event fires after a message has been sent using either SendMessage or SendData. The following parameters are available within this event:

• Destination: The destination the message was sent to.
• Data: The message's payload.
• ContentType: The content type of the message (always empty for messages sent with SendData).

ReadyToSend Event (IPWorksMQ_STOMP Class)

Fired when the class is ready to send data.

Object Oriented Interface

public function fireReadyToSend($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 8, array($this, 'fireReadyToSend'));

Parameter List

Remarks

The ReadyToSend event indicates that the underlying TCP/IP subsystem is ready to accept data after a call to SendData or SendMessage fails due to a WOULDBLOCK condition. The event is also fired immediately after a connection to the remote host is established.

ReceiptIn Event (IPWorksMQ_STOMP Class)

Fires when the class receives a receipt from the server.

Object Oriented Interface

public function fireReceiptIn($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 9, array($this, 'fireReceiptIn'));

Parameter List

 'receiptid'

Remarks

This event fires anytime the class receives a receipt (that is, a confirmation that the server has received one or more frames) from the server. The ReceiptId parameter reflects the value of the receipt-id header in the incoming RECEIPT frame.

Note that receipts are cumulative, and a STOMP server is not required to send back discrete receipts for each frame it receives that has a receipt header. For example, if the class has sent four message frames with the following receipt header values (in chronological order):

1. SEND-3
2. SEND-4
3. SEND-5
4. SEND-6

Refer to RequestReceipts for more information about receipts.

ReceiptOut Event (IPWorksMQ_STOMP Class)

Fires when the class sends a STOMP frame that includes a 'receipt' header.

Object Oriented Interface

public function fireReceiptOut($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 10, array($this, 'fireReceiptOut'));

Parameter List

 'receiptid'

Remarks

This event fires anytime the class sends any STOMP frame that includes a receipt header on it. The ReceiptId parameter reflects the value of the receipt header.

Having a receipt header on an outgoing frame indicates to the server that it should send back a receipt to confirm that it has received the frame (though it is not required to do so immediately; see ReceiptIn for details). Anytime the server sends back a receipt, the ReceiptIn event will fire.

Refer to RequestReceipts for more information about receipts.

SSLServerAuthentication Event (IPWorksMQ_STOMP Class)

Fired after the server presents its certificate to the client.

Object Oriented Interface

public function fireSSLServerAuthentication($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 11, array($this, 'fireSSLServerAuthentication'));

Parameter List

 'certencoded'
 'certsubject'
 'certissuer'
 'status'
 '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 (IPWorksMQ_STOMP Class)

Fired when secure connection progress messages are available.

Object Oriented Interface

public function fireSSLStatus($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 12, array($this, 'fireSSLStatus'));

Parameter List

 'message'

Remarks

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

Subscribed Event (IPWorksMQ_STOMP Class)

Fired when the class has subscribed to a message destination on the server.

Object Oriented Interface

public function fireSubscribed($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 13, array($this, 'fireSubscribed'));

Parameter List

 'id'
 'destination'
 'requireacks'

Remarks

This event fires each time the class has subscribed to a message destination on the server. The following parameters are available within this event:

• Id: The Id used to identify the subscription.
• Destination: The message destination on the server which the subscription is associated with.
• RequireAcks: Whether messages the class receives as a result of the subscription will require acknowledgments to be sent back to the server.

Unsubscribed Event (IPWorksMQ_STOMP Class)

Fired when the class has unsubscribed from a message destination on the server.

Object Oriented Interface

public function fireUnsubscribed($param);

Procedural Interface

ipworksmq_stomp_register_callback($res, 14, array($this, 'fireUnsubscribed'));

Parameter List

 'id'
 'destination'

Remarks

This event fires each time the class has unsubscribed from a message destination on the server. The following parameters are available within this event:

• Id: The Id that was used to identify the subscription.
• Destination: The message destination on the server which the subscription was associated with.
