Detailed Description

A client uses a IMessageProducer object to send messages to a destination.

A IMessageProducer object is created by passing a IDestination object to a message-producer creation method supplied by a session.

MessageProducer is the parent interface for all message producers.

A client also has the option of creating a message producer without supplying a destination. In this case, a destination must be provided with every send operation. A typical use for this kind of message producer is to send replies to requests using the request's JMSReplyTo destination.

A client can specify a default delivery mode, priority, and time to live for messages sent by a message producer. It can also specify the delivery mode, priority, and time to live for an individual message.

A client can specify a time-to-live value in milliseconds for each message it sends. This value defines a message expiration time that is the sum of the message's time-to-live and the GMT when it is sent (for transacted sends, this is the time the client sends the message, not the time the transaction is committed).

Member Function Documentation

CheckClosed()

TBTMessageProducer::CheckClosed ( )

protected

Check if the instance of this producer has been closed.

Exceptions

IllegalStateException

Close()

TBTMessageProducer::Close

(

)

Closes the message producer.

Exceptions

EMQException

if the provider fails to close the producer due to some internal error.

Send() [1/4]

TBTMessageProducer::Send	(	const IDestination	Destination,
		const IMessage	Message
	)

Sends a message to a destination for an unidentified message producer.

Uses the MessageProducer's default delivery mode, priority, and time to live.

Typically, a message producer is assigned a destination at creation time; however, the API also supports unidentified message producers, which require that the destination be supplied every time a message is sent.

Parameters

Destination	the destination to send this message to
Message	the message to send

Exceptions

EMQException

if the provider fails to send the message due to some internal error.

Send() [2/4]

TBTMessageProducer::Send	(	const IDestination	Destination,
		const IMessage	Message,
		const TJMSDeliveryMode	DeliveryMode,
		const Integer	Priority,
		const Integer	TimeToLive
	)

Sends a message to a destination for an unidentified message producer, specifying delivery mode, priority and time to live.

Typically, a message producer is assigned a destination at creation time; however, the API also supports unidentified message producers, which require that the destination be supplied every time a message is sent.

Parameters

Destination	the destination to send this message to
Message	the message to send
DeliveryMode	the delivery mode to use
Priority	the priority for this message
TimeToLive	the message's lifetime (in milliseconds)

Exceptions

EMQException

if the provider fails to send the message due to some internal error.

Send() [3/4]

TBTMessageProducer::Send

(

const IMessage

Message

)

Sends a message using the MessageProducer's default delivery mode, priority, and time to live.

Parameters

Message

the message to send

Exceptions

EMQException

if the provider fails to send the message due to some internal error.

Send() [4/4]

TBTMessageProducer::Send	(	const IMessage	Message,
		const TJMSDeliveryMode	DeliveryMode,
		const Integer	Priority,
		const Integer	TimeToLive
	)

Sends a message to the destination, specifying delivery mode, priority, and time to live.

Parameters

Message	the message to send
DeliveryMode	the delivery mode to use
Priority	the priority for this message
TimeToLive	the message's lifetime (in milliseconds)

Exceptions

EMQException

if the provider fails to send the message due to some internal error.
