Interface ServiceListener

All Superinterfaces:

public interface ServiceListener
extends java.util.EventListener

A ServiceEvent listener.

ServiceListener is a listener interface that may be implemented by a bundle developer.

A ServiceListener object is registered with the Framework using the BundleContext.addServiceListener method. ServiceListener objects are called with a ServiceEvent object when a service has been registered or 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 the service was registered under.
