public class VmComponent
extends SedaComponent

An implementation of the VM components for asynchronous SEDA exchanges on a BlockingQueue within the classloader tree containing the camel-core.jar. i.e. to handle communicating across CamelContext instances and possibly across web application contexts, providing that camel-core.jar is on the system classpath.

Method Detail

getQueues

public Map<String,QueueReference> getQueues()

Overrides:

getQueues in class SedaComponent

getQueueReference

public QueueReference getQueueReference(String key)

Overrides:

getQueueReference in class SedaComponent

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 DefaultComponent

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 SedaComponent

Throws:

Exception

See Also:

ServiceSupport.doStart()

createEndpoint

protected Endpoint createEndpoint(String uri,
                      String remaining,
                      Map<String,Object> parameters)
                           throws Exception

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

Overrides:

createEndpoint in class SedaComponent

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 - is thrown if error creating the endpoint
