Interface ServiceControllerAction

All Superinterfaces:

Action

All Known Implementing Classes:

DummyService

public interface ServiceControllerAction
extends Action

Action for controlling services installed under the extensions system. A factory may return the same or a different action on each invokation, but the action must control the same service. The actions should not store state internally. Eg. if there are two different controllers for the same extension the isRunning() method should always return the same value on both of them and invoking start() or stop() on one controller should be immediately visible on the second controller.
