public class UntilSuccessful
extends AbstractOutboundRouter
implements UntilSuccessfulConfiguration

UntilSuccessful attempts to route a message to the message processor it contains. Routing is considered successful if no exception has been raised and, optionally, if the response matches an expression. UntilSuccessful internal route can be executed synchronously or asynchronously depending on the threading profile defined on it. By default, if no threading profile is defined, then it will use the default threading profile configuration for the application. This means that the default behavior is to process asynchronously. UntilSuccessful can optionally be configured to synchronously return an acknowledgment message when it has scheduled the event for processing. UntilSuccessful is backed by a ListableObjectStore for storing the events that are pending (re)processing. To execute until-successful asynchronously the threading profile defined on it must have doThreading attribute set with true value. To execute until-successful synchronously the threading profile defined on it must have doThreading attribute set with false value.

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 AbstractOutboundRouter

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 AbstractOutboundRouter

Throws:

MuleException

createScheduledRetriesPool

public ScheduledThreadPoolExecutor createScheduledRetriesPool(String threadPrefix)

Specified by:

createScheduledRetriesPool in interface UntilSuccessfulConfiguration

Parameters:

threadPrefix - the prefix for the name of the threads of this executor's pool.

Returns:

an executor responsible for calling the retries for this processing strategy.

stop

public void stop()
          throws MuleException

Specified by:

stop in interface Stoppable

Overrides:

stop in class AbstractOutboundRouter

Throws:

MuleException

isMatch

public boolean isMatch(MuleMessage message)
                throws MuleException

Description copied from interface: Matchable

Determines if the event should be processed

Specified by:

isMatch in interface Matchable

Parameters:

message - the current message to evaluate

Returns:

true if the event should be processed by this router

Throws:

MuleException - if the event cannot be evaluated

route

protected MuleEvent route(MuleEvent event)
                   throws MessagingException

Specified by:

route in class AbstractOutboundRouter

Throws:

MessagingException
