com.j_spaces.jms.GSTemporaryTopicImpl

All Implemented Interfaces:

Serializable, Remote, javax.jms.Destination, javax.jms.TemporaryTopic, javax.jms.Topic

public class GSTemporaryTopicImpl
extends GSTopicImpl
implements javax.jms.TemporaryTopic, Serializable

GigaSpaces implementation of the javax.jms.TemporaryTopic interface. This class represents a queue which provides it's messages exclusively to one consumer at a time. In our case, the Topic name represents the GigaSpaces entry name. We use the same space proxy we obtained in the session and we write another External Entry, which will have a class name of 'TempTopic'. The only message consumers that can consume from a temporary destination are those created by the same connection that created the destination. Any message producer can send to the temporary destination. If you close the connection that a temporary destination belongs to, the destination is closed and its contents lost. You can use temporary destinations to implement a simple request/reply mechanism. If you create a temporary destination and specify it as the value of the JMSReplyTo message header field when you send a message, the consumer of the message can use the value of the JMSReplyTo field as the destination to which it sends a reply and can also reference the original request by setting the JMSCorrelationID header field of the reply message to the value of the JMSMessageID header field of the request.
