@Service
 @Named
 @RunLevel(value=10)
public class ListenerService
extends AbstractServerService

Manage the lifecycle of all of the configured non-admin channels. The admin channels and listeners are managed by the AdminPortService. TODO: would like to rename this to ChannelListenerService and move it to the server-channels package The listeners (non-admin) are bound and then enabled via:

 ListenerService.start()
 EnableListenersIfAdminChannelAbsentService.start()
 or
 EnableListenersService.start()
 

There may be some period of delay between the call to createAndBind the listeners and the call to enableServerSockets the listeners depending on the setting of Server.ListenersBindEarly. At shutdown EnableListenersService.stop() or EnableListenersIfAdminChannelAbsentService.stop() stops the non-admin listeners and the ListenerService does nothing, i.e. as early as possible. These functions are also called by the ChannelService to dynamically start and stop the Channels. Ideally the logic from ChannelListenerManager would exist in the ListenerService itself. However, the services are a bit of a mess and need to iron out some issues in order to bring this logic up and move to the correct packages. This is introduced as a temporary stop gap in order to introduce the correct functionality without having to resolve several different issues with regard to services.

Method Detail

start

public void start()
           throws ServiceFailureException

Description copied from interface: ServerService

This method starts the service. The service is fully functioning and available to other services after this method returns. This is a blocking operation. The service should return only after it has started. It should throw ServiceFailureException if it is unable to complete the start operation.

This method can be called more than once but not concurrently. Here are the conditions under which start() can be called:

During server startup After stop completes without exception After halt completes without exception After halt completes without exception even when a preceding stop threw an exception

Specified by:

start in interface ServerService

Overrides:

start in class AbstractServerService

Throws:

ServiceFailureException - service is unable to start due to an internal error condition. The service is not available if this exception is thrown. The service should cleanup its state before throwing this exception. No further callbacks will be issued after this exception is thrown.
