Description copied from class: DefaultComponent

A factory method allowing derived components to create a new endpoint from the given URI, remaining path and optional parameters

Specified by:

createEndpoint in class DefaultComponent

Parameters:

uri - the full URI of the endpoint

remaining - the remaining part of the URI without the query parameters or component prefix

parameters - the optional parameters passed in

Returns:

a newly created endpoint or null if the endpoint cannot be created based on the inputs

Throws:

Exception

getQueueKey

public String getQueueKey(String uri)

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 DefaultComponent

Throws:

Exception
