Class ClusterizableMessageSourceWrapper

java.lang.Object
  org.mule.source.ClusterizableMessageSourceWrapper

All Implemented Interfaces:

FlowConstructAware, MuleContextAware, ClusterNodeNotificationListener, ServerNotificationListener, Disposable, Initialisable, Lifecycle, Startable, Stoppable, MessageSource

public class ClusterizableMessageSourceWrapper
extends Object
implements MessageSource, Lifecycle, ClusterNodeNotificationListener, MuleContextAware, FlowConstructAware

Wraps a ClusterizableMessageSource in order to manage the lifecycle of the wrapped instance differently depending if the node is primary or not inside a cluster. Non clustered nodes are always primary.

Method Detail

setListener

public void setListener(MessageProcessor listener)

Description copied from interface: MessageSource

Set the MessageProcessor listener on a message source which will be invoked when a message is received or generated.

Specified by:

setListener in interface MessageSource

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

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.

Specified by:

dispose in interface Disposable

onNotification

public void onNotification(ServerNotification notification)

Specified by:

onNotification in interface ServerNotificationListener

registerNotificationListener

protected void registerNotificationListener()

unregisterNotificationListener

protected void unregisterNotificationListener()

setFlowConstruct

public void setFlowConstruct(FlowConstruct flowConstruct)

Specified by:

setFlowConstruct in interface FlowConstructAware

setMuleContext

public void setMuleContext(MuleContext context)

Specified by:

setMuleContext in interface MuleContextAware

isStarted

public boolean isStarted()
