BundleContext getBundleContext()
java.lang.String getFilter()
null if the listener was added without a filter.boolean isRemoved()
false indicating the
listener has been added but has not been removed. After the listener
has been removed, this method must always return true.
There is an extremely rare case in which removed notification to
ListenerHooks can be made before added notification if two
threads are racing to add and remove the same service listener.
Because ListenerHooks are called synchronously during service
listener addition and removal, the Framework cannot guarantee
in-order delivery of added and removed notification for a given
service listener. This method can be used to detect this rare
occurrence.
false if the listener has not been been removed,
true otherwise.boolean equals(java.lang.Object obj)
ListenerInfo to another ListenerInfo.
Two ListenerInfos are equals if they refer to the same
listener for a given addition and removal life cycle. If the same
listener is added again, it must have a different
ListenerInfo which is not equal to this ListenerInfo.
equals in class java.lang.Objectobj - The object to compare against this ListenerInfo.
true if the other object is a ListenerInfo
object and both objects refer to the same listener for a
given addition and removal life cycle.int hashCode()
ListenerInfo.
hashCode in class java.lang.ObjectListenerInfo.
