Interface WireAdminListener

public interface WireAdminListener

Listener for Wire Admin Events.

WireAdminListener objects are registered with the Framework service registry and are notified with a WireAdminEvent object when an event is broadcast.

WireAdminListener objects can inspect the received WireAdminEvent object to determine its type, the Wire object with which it is associated, and the Wire Admin service that broadcasts the event.

WireAdminListener objects must be registered with a service property WireConstants.WIREADMIN_EVENTS whose value is a bitwise OR of all the event types the listener is interested in receiving.

For example:

 Hashtable ht = new Hashtable();
 ht.put(WIREADMIN_EVENTS, mask);
 context.registerService(WireAdminListener.class.getName(), this, ht);
If a WireAdminListener object is registered without a service property WireConstants.WIREADMIN_EVENTS, then the WireAdminListener will receive no events.

Security Considerations. Bundles wishing to monitor WireAdminEvent objects will require ServicePermission[WireAdminListener,REGISTER] to register a WireAdminListener service. Since WireAdminEvent objects contain Wire objects, care must be taken in assigning permission to register a WireAdminListener service.
