ConnectionConsumer

public interface ConnectionConsumer

For application servers, Connection objects provide a special facility for creating a ConnectionConsumer (optional). The messages it is to consume are specified by a Destination and a message selector. In addition, a ConnectionConsumer must be given a ServerSessionPool to use for processing its messages.

Normally, when traffic is light, a ConnectionConsumer gets a ServerSession from its pool, loads it with a single message, and starts it. As traffic picks up, messages can back up. If this happens, a ConnectionConsumer can load each ServerSession with more than one message. This reduces the thread context switches and minimizes resource use at the expense of some serialization of message processing.

Fields Summary
Constructors Summary
Methods Summary
public void close()
Closes the connection consumer.
Since a provider may allocate some resources on behalf of a connection consumer outside the Java virtual machine, clients should close these resources when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.
exception
JMSException if the JMS provider fails to release resources on behalf of the connection consumer or fails to close the connection consumer.
public ServerSessionPool getServerSessionPool()
Gets the server session pool associated with this connection consumer.
return
the server session pool used by this connection consumer
exception
JMSException if the JMS provider fails to get the server session pool associated with this consumer due to some internal error.
