/** A client uses a TopicPublisher object to publish messages on a
* topic. A TopicPublisher object is the publish-subscribe form
* of a message producer.
*
* Normally, the Topic is specified when a
* TopicPublisher is created. In this case, an attempt to use
* the publish methods for an unidentified
* TopicPublisher will throw a
* java.lang.UnsupportedOperationException.
*
*
If the TopicPublisher is created with an unidentified
* Topic, an attempt to use the publish methods that
* assume that the Topic has been identified will throw a
* java.lang.UnsupportedOperationException.
*
*
During the execution of its publish method,
* a message must not be changed by other threads within the client.
* If the message is modified, the result of the publish is
* undefined.
*
*
After publishing a message, a client may retain and modify it
* without affecting the message that has been published. The same message
* object may be published multiple times.
*
*
The following message headers are set as part of publishing a
* message: JMSDestination, JMSDeliveryMode,
* JMSExpiration, JMSPriority,
* JMSMessageID and JMSTimeStamp.
* When the message is published, the values of these headers are ignored.
* After completion of the publish, the headers hold the values
* specified by the method publishing the message. It is possible for the
* publish method not to set JMSMessageID and
* JMSTimeStamp if the
* setting of these headers is explicitly disabled by the
* MessageProducer.setDisableMessageID or
* MessageProducer.setDisableMessageTimestamp method.
*
*
Creating a MessageProducer provides the same features as
* creating a TopicPublisher. A MessageProducer object is
* recommended when creating new code. The TopicPublisher is
* provided to support existing code.
*
*
Because TopicPublisher inherits from
* MessageProducer, it inherits the
* send methods that are a part of the MessageProducer
* interface. Using the send methods will have the same
* effect as using the
* publish methods: they are functionally the same.
