Class JmsPoolConnection

java.lang.Object

org.messaginghub.pooled.jms.JmsPoolConnection

All Implemented Interfaces:

AutoCloseable, javax.jms.Connection, javax.jms.QueueConnection, javax.jms.TopicConnection, JmsPoolSessionEventListener

public class JmsPoolConnection
extends Object
implements javax.jms.TopicConnection, javax.jms.QueueConnection, JmsPoolSessionEventListener, AutoCloseable

Represents a proxy Connection which is-a TopicConnection and QueueConnection which is pooled and on close() will return its reference to the ConnectionPool backing it. NOTE this implementation is only intended for use when sending messages. It does not deal with pooling of consumers.

onTemporaryQueueCreate

public void onTemporaryQueueCreate(javax.jms.TemporaryQueue tempQueue)

Description copied from interface: JmsPoolSessionEventListener

Called on successful creation of a new TemporaryQueue.

Specified by:

onTemporaryQueueCreate in interface JmsPoolSessionEventListener

Parameters:

tempQueue - The TemporaryQueue just created.

onTemporaryTopicCreate

public void onTemporaryTopicCreate(javax.jms.TemporaryTopic tempTopic)

Description copied from interface: JmsPoolSessionEventListener

Called on successful creation of a new TemporaryTopic.

Specified by:

onTemporaryTopicCreate in interface JmsPoolSessionEventListener

Parameters:

tempTopic - The TemporaryTopic just created.

onSessionClosed

public void onSessionClosed(JmsPoolSession session)

Description copied from interface: JmsPoolSessionEventListener

Called when the PooledSession is closed.

Specified by:

onSessionClosed in interface JmsPoolSessionEventListener

Parameters:

session - The PooledSession that has been closed.

getConnection

public javax.jms.Connection getConnection()
                                   throws javax.jms.JMSException

Throws:

javax.jms.JMSException

toString

public String toString()

Overrides:

toString in class Object

cleanupConnectionTemporaryDestinations

protected void cleanupConnectionTemporaryDestinations()

Remove all of the temporary destinations created for this connection. This is important since the underlying connection may be reused over a long period of time, accumulating all of the temporary destinations from each use. However, from the perspective of the lifecycle from the client's view, close() closes the connection and, therefore, deletes all of the temporary destinations created.

cleanupAllLoanedSessions

protected void cleanupAllLoanedSessions()

The PooledSession tracks all Sessions that it created and now we close them. Closing the PooledSession will return the internal Session to the Pool of Session after cleaning up all the resources that the Session had allocated for this PooledConnection.

getNumSessions

public int getNumSessions()
                   throws javax.jms.JMSException

Returns:

the total number of Pooled session including idle sessions that are not currently loaned out to any client.

Throws:

javax.jms.JMSException - if the connection has been closed.

getNumActiveSessions

public int getNumActiveSessions()
                         throws javax.jms.JMSException

Returns:

the number of Sessions that are currently checked out of this Connection's session pool.

Throws:

javax.jms.JMSException - if the connection has been closed.

getNumtIdleSessions

public int getNumtIdleSessions()
                        throws javax.jms.JMSException

Returns:

the number of Sessions that are idle in this Connection's sessions pool.

Throws:

javax.jms.JMSException - if the connection has been closed.

checkClosed

protected void checkClosed()
                    throws javax.jms.IllegalStateException

Throws:

javax.jms.IllegalStateException
