route - the route

createUoW

public UnitOfWork createUoW(Exchange exchange)
                     throws Exception

If the consumer needs to defer done the UnitOfWork on the processed Exchange then this method should be executed when the consumer is finished processing the message.

Parameters:

exchange - the exchange

getEndpoint

public Endpoint getEndpoint()

Description copied from interface: EndpointAware

Gets the endpoint associated with an object. It's the endpoint for sending to for components like Producer or for consuming from for components like Consumer or Route

Specified by:

getEndpoint in interface EndpointAware

Returns:

the endpoint

getProcessor

public Processor getProcessor()

getAsyncProcessor

public AsyncProcessor getAsyncProcessor()

Provides an AsyncProcessor interface to the configured processor on the consumer. If the processor does not implement the interface, it will be adapted so that it does.

getExceptionHandler

public ExceptionHandler getExceptionHandler()

setExceptionHandler

public void setExceptionHandler(ExceptionHandler exceptionHandler)

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()

doStart

protected void doStart()
                throws Exception
