## javax.jms
Interface 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.

  `Connection.createConnectionConsumer(javax.jms.Destination, java.lang.String, javax.jms.ServerSessionPool, int)`, `Connection.createDurableConnectionConsumer(javax.jms.Topic, java.lang.String, java.lang.String, javax.jms.ServerSessionPool, int)`, `QueueConnection.createConnectionConsumer(javax.jms.Queue, java.lang.String, javax.jms.ServerSessionPool, int)`, `TopicConnection.createConnectionConsumer(javax.jms.Topic, java.lang.String, javax.jms.ServerSessionPool, int)`, `TopicConnection.createDurableConnectionConsumer(javax.jms.Topic, java.lang.String, java.lang.String, javax.jms.ServerSessionPool, int)`

Method Summary
`void` | `close()` Closes the connection consumer.
`ServerSessionPool` | `getServerSessionPool()` Gets the server session pool associated with this connection consumer.

Method Detail

### getServerSessionPool

    ServerSessionPool getServerSessionPool()
                                           throws JMSException

  Gets the server session pool associated with this connection consumer.

  Returns:
    the server session pool used by this connection consumer
  Throws:
    `JMSException` - if the JMS provider fails to get the server session pool associated with this consumer due to some internal error.

### close

    void close()
               throws JMSException

  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.

  Throws:
    `JMSException` - if the JMS provider fails to release resources on behalf of the connection consumer or fails to close the connection consumer.
