KMConnectionConsumer Class Reference
Inherits from | KCObject : NSObject |
Declared in | KMConnectionConsumer.h |
Overview
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.
Tasks
-
– serverSessionPool
Gets the server session pool associated with this connection consumer.
-
– close
Closes the connection consumer.
Instance Methods
close
Closes the connection consumer.
- (void)close
Discussion
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.
Exceptions
- KMJMSException
if the JMS provider fails to release resources on behalf of the connection consumer or fails to close the connection consumer.
