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:
Integer mask = new Integer( WIRE_TRACE | WIRE_CONNECTED | WIRE_DISCONNECTED ); 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[REGISTER,WireAdminListener] to register a WireAdminListener service. Since WireAdminEvent objects contain Wire objects, care must be taken in assigning permission to register a WireAdminListener service.
