Method Detail

processNextAsync

protected void processNextAsync(MuleEvent event)
                         throws MuleException
Overrides:
processNextAsync in class AsyncInterceptingMessageProcessor
Throws:
MuleException

isStatsEnabled

protected boolean isStatsEnabled()

enqueue

protected void enqueue(MuleEvent event)
                throws java.lang.Exception
Throws:
java.lang.Exception

dequeue

protected MuleEvent dequeue()
                     throws java.lang.Exception
Throws:
java.lang.Exception

run

public void run()
While the service isn't stopped this runs a continuous loop checking for new events in the queue.

Specified by:
run in interface java.lang.Runnable

isQueuePersistent

protected boolean isQueuePersistent()
Are the events in the SEDA queue persistent?


getQueueSize

public int getQueueSize()

getQueueName

protected java.lang.String getQueueName()

getStageName

protected java.lang.String getStageName()

getStageDescription

protected java.lang.String getStageDescription()

waitIfPaused

protected void waitIfPaused()
                     throws java.lang.InterruptedException
Throws:
java.lang.InterruptedException

release

public void release()
Specified by:
release in interface javax.resource.spi.work.Work

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
Overrides:
start in class AsyncInterceptingMessageProcessor
Throws:
MuleException

stop

public void stop()
          throws MuleException
Specified by:
stop in interface Stoppable
Overrides:
stop in class AsyncInterceptingMessageProcessor
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
