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_EVENTSwhose 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[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.
