Class DelegateQueueManager

java.lang.Object
  org.mule.util.queue.DelegateQueueManager

All Implemented Interfaces:

MuleContextAware, Disposable, Initialisable, Lifecycle, Startable, Stoppable, QueueManager

public class DelegateQueueManager
extends Object
implements QueueManager, Lifecycle, MuleContextAware

Delegates every call to the real QueueManager. If there's a system property with mule.queue.objectstoremode=true then the old version of the QueueManager will be used. This is to maintain backward compatibility in case a customer is relaying on ObjectStore for queue store customization.

Returns:

session for retrieving queues and handle transactions

setDefaultQueueConfiguration

public void setDefaultQueueConfiguration(QueueConfiguration config)

Description copied from interface: QueueManager

Sets the default QueueConfiguration for any created Queue for which a custom configuration hasn't been specified

Specified by:

setDefaultQueueConfiguration in interface QueueManager

Parameters:

config - an instance of QueueConfiguration

setQueueConfiguration

public void setQueueConfiguration(String queueName,
                                  QueueConfiguration config)

Description copied from interface: QueueManager

Specifies a QueueConfiguration for the queue which name matches queueName

Specified by:

setQueueConfiguration in interface QueueManager

Parameters:

queueName - the name of a Queue

config - an instance of QueueConfiguration

start

public void start()
           throws MuleException

Specified by:

start in interface Startable

Throws:

MuleException

stop

public void stop()
          throws MuleException

Specified by:

stop in interface Stoppable

Throws:

MuleException

dispose

public void dispose()

Description copied from interface: Disposable

A lifecycle method where implementor should free up any resources. If an exception is thrown it should just be logged and processing should continue. This method should not throw Runtime exceptions.

initialise

public void initialise()
                throws InitialisationException

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:

initialise in interface Initialisable

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from

setMuleContext

public void setMuleContext(MuleContext context)

Specified by:

setMuleContext in interface MuleContextAware

isOldModeEnabled

public static boolean isOldModeEnabled()
