public interface ServiceListener
extends java.util.EventListener
ServiceEvent listener. ServiceListener is a listener
interface that may be implemented by a bundle developer. When a
ServiceEvent is fired, it is synchronously delivered to a
ServiceListener. The Framework may deliver ServiceEvent
objects to a ServiceListener out of order and may concurrently call
and/or reenter a ServiceListener.
A ServiceListener object is registered with the Framework using the
BundleContext.addServiceListener method. ServiceListener
objects are called with a ServiceEvent object when a service is
registered, modified, or is in the process of unregistering.
ServiceEvent object delivery to ServiceListener objects is
filtered by the filter specified when the listener was registered. If the
Java Runtime Environment supports permissions, then additional filtering is
done. ServiceEvent objects are only delivered to the listener if the
bundle which defines the listener object's class has the appropriate
ServicePermission to get the service using at least one of the named
classes under which the service was registered.
ServiceEvent object delivery to ServiceListener objects is
further filtered according to package sources as defined in
ServiceReference.isAssignableTo(Bundle, String).
