public class TryMessageProcessor
extends AbstractMessageProcessorOwner
implements Processor

Wraps the invocation of a list of nested processors Processor with a transaction. If the TransactionConfig is null then no transaction is used and the next Processor is invoked directly.

TryMessageProcessor

public TryMessageProcessor()

Method Detail

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

setExceptionListener

public void setExceptionListener(MessagingExceptionHandler exceptionListener)

Configures the MessagingExceptionHandler that should be used to handle any errors that occur in this scope.

Parameters:

exceptionListener - the MessagingExceptionHandler to be used.

setTransactionConfig

public void setTransactionConfig(MuleTransactionConfig transactionConfig)

Configures the TransactionConfig that that defines the transactional behaviour of this scope.

Parameters:

transactionConfig - the TransactionConfig to be used.

getTransactionConfig

public MuleTransactionConfig getTransactionConfig()

Obtain the TransactionConfig configured that defines transactional behaviour of this scope.

Returns:

the configured TransactionConfig.

setMessageProcessors

public void setMessageProcessors(List<Processor> processors)

Configure the nested Processor's that error handling and transactional behaviour should be applied to.

Parameters:

processors -

initialise

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

Specified by:

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

Specified by:

dispose in interface org.mule.runtime.api.lifecycle.Disposable

Overrides:

dispose in class AbstractMuleObjectOwner<Processor>

start

Specified by:

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

Overrides:

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

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>
