Class AsyncDelegateMessageProcessor

java.lang.Object

org.mule.processor.AbstractMuleObjectOwner<MessageProcessor>

org.mule.processor.AbstractMessageProcessorOwner

org.mule.processor.AsyncDelegateMessageProcessor

All Implemented Interfaces:

AnnotatedObject, FlowConstructAware, MuleContextAware, MessagingExceptionHandlerAware, Disposable, Initialisable, Lifecycle, Startable, Stoppable, NonBlockingSupported, MessageProcessor, MessageProcessorContainer

public class AsyncDelegateMessageProcessor
extends AbstractMessageProcessorOwner
implements MessageProcessor, Initialisable, Startable, Stoppable, NonBlockingSupported

Processes MuleEvent's asynchronously using a MuleWorkManager to schedule asynchronous processing of MessageProcessor delegate configured the next MessageProcessor. The next MessageProcessor is therefore be executed in a different thread regardless of the exchange-pattern configured on the inbound endpoint. If a transaction is present then an exception is thrown.

AsyncDelegateMessageProcessor

public AsyncDelegateMessageProcessor(MessageProcessor delegate,
                             ProcessingStrategy processingStrategy,
                             String name)

Method Detail

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

Overrides:

initialise in class AbstractMuleObjectOwner<MessageProcessor>

Throws:

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

RecoverableException - if an error occurs that can be recovered from

process

public MuleEvent process(MuleEvent event)
                  throws MuleException

Description copied from interface: MessageProcessor

Invokes the MessageProcessor.

Specified by:

process in interface MessageProcessor

Parameters:

event - MuleEvent to be processed

Returns:

optional response MuleEvent

Throws:

MuleException

setDelegate

public void setDelegate(MessageProcessor delegate)

getOwnedMessageProcessors

protected List<MessageProcessor> getOwnedMessageProcessors()

Specified by:

getOwnedMessageProcessors in class AbstractMessageProcessorOwner

getProcessingStrategy

public ProcessingStrategy getProcessingStrategy()

addMessageProcessorPathElements

public void addMessageProcessorPathElements(MessageProcessorPathElement pathElement)

Description copied from interface: MessageProcessorContainer

Add the child nodes to the path element tree.

Specified by:

addMessageProcessorPathElements in interface MessageProcessorContainer

Overrides:

addMessageProcessorPathElements in class AbstractMessageProcessorOwner
