Method Detail

poll

protected int poll()
            throws Exception

Description copied from class: ScheduledPollConsumer

The polling method which is invoked periodically to poll this consumer

Specified by:

poll in class ScheduledPollConsumer

Returns:

number of messages polled, will be 0 if no message was polled at all.

Throws:

Exception - can be thrown if an exception occurred during polling

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.

Overrides:

doStart in class ScheduledPollConsumer

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.

Overrides:

doStop in class ScheduledPollConsumer

Throws:

Exception

ServiceSupport.doStart()
