public abstract class AbstractRedeliveryPolicy
extends AbstractInterceptingMessageProcessor
implements MessageProcessor, Lifecycle, MuleContextAware, FlowConstructAware

Implement a redelivery policy for Mule. This is similar to JMS retry policies that will redeliver a message a maximum number of times. If this maximum is exceeded, the message is sent to a dead letter queue, Here, if the processing of the messages fails too often, the message is sent to the failedMessageProcessor MP, whence success is force to be returned, to allow the message to be considered "consumed".

Method Detail

setFlowConstruct

public void setFlowConstruct(FlowConstruct flowConstruct)

Specified by:

setFlowConstruct in interface FlowConstructAware

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

getMaxRedeliveryCount

public int getMaxRedeliveryCount()

setMaxRedeliveryCount

public void setMaxRedeliveryCount(int maxRedeliveryCount)

getTheFailedMessageProcessor

public MessageProcessor getTheFailedMessageProcessor()

setDeadLetterQueue

public void setDeadLetterQueue(MessageProcessorFilterPair failedMessageProcessorPair)
