All Implemented Interfaces:

Function<org.reactivestreams.Publisher<Event>,org.reactivestreams.Publisher<Event>>, org.mule.runtime.api.lifecycle.Disposable, org.mule.runtime.api.lifecycle.Initialisable, org.mule.runtime.api.lifecycle.Lifecycle, org.mule.runtime.api.lifecycle.Startable, org.mule.runtime.api.lifecycle.Stoppable, org.mule.runtime.api.meta.AnnotatedObject, FlowConstructAware, MuleContextAware, MessagingExceptionHandlerAware, Processor, ReactiveProcessor

public class AsyncDelegateMessageProcessor
extends AbstractMessageProcessorOwner
implements Processor, org.mule.runtime.api.lifecycle.Initialisable, org.mule.runtime.api.lifecycle.Startable, org.mule.runtime.api.lifecycle.Stoppable, MessagingExceptionHandlerAware

Processes Event's asynchronously using a ProcessingStrategy to schedule asynchronous processing of MessageProcessor delegate configured the next Processor. The next Processor 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.

Method Detail

initialise

public void initialise()
                throws org.mule.runtime.api.lifecycle.InitialisationException

Specified by:

initialise in interface org.mule.runtime.api.lifecycle.Initialisable

Overrides:

initialise in class AbstractMuleObjectOwner<Processor>

Throws:

org.mule.runtime.api.lifecycle.InitialisationException

start

public void start()
           throws org.mule.runtime.api.exception.MuleException

Specified by:

start in interface org.mule.runtime.api.lifecycle.Startable

Overrides:

start in class AbstractMuleObjectOwner<Processor>

Throws:

org.mule.runtime.api.exception.MuleException

stop

public void stop()
          throws org.mule.runtime.api.exception.MuleException

Specified by:

stop in interface org.mule.runtime.api.lifecycle.Stoppable

Overrides:

stop in class AbstractMuleObjectOwner<Processor>

Throws:

org.mule.runtime.api.exception.MuleException

process

public Event process(Event event)
              throws org.mule.runtime.api.exception.MuleException

Description copied from interface: Processor

Invokes the MessageProcessor.

Specified by:

process in interface Processor

Parameters:

event - MuleEvent to be processed

Returns:

optional response MuleEvent

Throws:

org.mule.runtime.api.exception.MuleException

apply

public org.reactivestreams.Publisher<Event> apply(org.reactivestreams.Publisher<Event> publisher)

Description copied from interface: Processor

Applies a Publisher function transforming a stream of Event's.

The default implementation delegates to Processor.process(Event) and will:

1. propagate any exception thrown
2. drop events if invocation of Processor.process(Event) returns null.

Specified by:

apply in interface Function<org.reactivestreams.Publisher<Event>,org.reactivestreams.Publisher<Event>>

Specified by:

apply in interface Processor

Parameters:

publisher - the event stream to transform

Returns:

the transformed event stream

getOwnedMessageProcessors

protected List<Processor> getOwnedMessageProcessors()

Specified by:

getOwnedMessageProcessors in class AbstractMessageProcessorOwner

setMessagingExceptionHandler

public void setMessagingExceptionHandler(MessagingExceptionHandler messagingExceptionHandler)

Specified by:

setMessagingExceptionHandler in interface MessagingExceptionHandlerAware

Overrides:

setMessagingExceptionHandler in class AbstractMuleObjectOwner<Processor>
