Class RecipientList

java.lang.Object
  org.apache.camel.support.ServiceSupport
      org.apache.camel.processor.RecipientList

All Implemented Interfaces:

AsyncProcessor, Processor, Service, ShutdownableService, StatefulService, SuspendableService

public class RecipientList
extends ServiceSupport
implements AsyncProcessor

Implements a dynamic Recipient List pattern where the list of actual endpoints to send a message exchange to are dependent on some dynamic expression.

Method Detail

toString

public String toString()

Overrides:

toString in class Object

process

public void process(Exchange exchange)
             throws Exception

Description copied from interface: Processor

Processes the message exchange

Specified by:

process in interface Processor

Parameters:

exchange - the message exchange

Throws:

Exception - if an internal processing error has occurred.

process

public boolean process(Exchange exchange,
                       AsyncCallback callback)

Description copied from interface: AsyncProcessor

Processes the message exchange. Similar to Processor.process(org.apache.camel.Exchange), but the caller supports having the exchange asynchronously processed.

If there was a failure processing then the caused Exception would be set on the Exchange.

Specified by:

process in interface AsyncProcessor

Parameters:

exchange - the message exchange

callback - the AsyncCallback will be invoked when the processing of the exchange is completed. If the exchange is completed synchronously, then the callback is also invoked synchronously. The callback should therefore be careful of starting recursive loop.

Returns:

(doneSync) true to continue execute synchronously, false to continue being executed asynchronously

See Also:

AsyncProcessorHelper.process(AsyncProcessor, Exchange, AsyncCallback)

sendToRecipientList

public boolean sendToRecipientList(Exchange exchange,
                                   Object recipientList,
                                   AsyncCallback callback)

Sends the given exchange to the recipient list

resolveEndpoint

protected Endpoint resolveEndpoint(Exchange exchange,
                                   Object recipient)

doStart

protected void doStart()
                throws Exception

Description copied from class: ServiceSupport

Implementations override this method to support customized start/stop.

Important: See ServiceSupport.doStop() for more details.

Specified by:

doStart in class ServiceSupport

Throws:

Exception

See Also:

ServiceSupport.doStop()

doStop

protected void doStop()
               throws Exception

Description copied from class: ServiceSupport

Implementations override this method to support customized start/stop.

Important: Camel will invoke this ServiceSupport.doStop() method when the service is being stopped. This method will also be invoked if the service is still in uninitialized state (eg has not been started). The method is always called to allow the service to do custom logic when the service is being stopped, such as when CamelContext is shutting down.

Specified by:

doStop in class ServiceSupport

Throws:

Exception

See Also:

ServiceSupport.doStart()

doShutdown

protected void doShutdown()
                   throws Exception

Description copied from class: ServiceSupport

Implementations override this method to perform customized shutdown.

Overrides:

doShutdown in class ServiceSupport

Throws:

Exception
