for more details.

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
- See Also:
ServiceSupport.doStart()
