Method Details

getBundle
-
getBundleContext
Description copied from interface:ListenerHook.ListenerInfo
Return the context of the bundle which added the listener.- Specified by:
getBundleContext
in interfaceListenerHook.ListenerInfo
- Returns:
- The context of the bundle which added the listener.
-
getListenerClass
-
getListener
-
getParsedFilter
-
getFilter
Description copied from interface:ListenerHook.ListenerInfo
Return the filter string with which the listener was added.- Specified by:
getFilter
in interfaceListenerHook.ListenerInfo
- Returns:
- The filter string with which the listener was added. This may
be
null
if the listener was added without a filter.
-
getSecurityContext
-
isRemoved
public boolean isRemoved()Description copied from interface:ListenerHook.ListenerInfo
Return the state of the listener for this addition and removal life cycle. Initially this method will returnfalse
indicating the listener has been added but has not been removed. After the listener has been removed, this method must always returntrue
.There is an extremely rare case in which removed notification to
ListenerHook
s can be made before added notification if two threads are racing to add and remove the same service listener. BecauseListenerHook
s 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.- Specified by:
isRemoved
in interfaceListenerHook.ListenerInfo
- Returns:
false
if the listener has not been been removed,true
otherwise.
-
equals
Description copied from interface:ListenerHook.ListenerInfo
Compares thisListenerInfo
to anotherListenerInfo
. TwoListenerInfo
s 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 differentListenerInfo
which is not equal to thisListenerInfo
.- Specified by:
equals
in interfaceListenerHook.ListenerInfo
- Overrides:
equals
in classObject
- Parameters:
obj
- The object to compare against thisListenerInfo
.- Returns:
true
if the other object is aListenerInfo
object and both objects refer to the same listener for a given addition and removal life cycle.
-
hashCode
public int hashCode()Description copied from interface:ListenerHook.ListenerInfo
Returns the hash code for thisListenerInfo
.- Specified by:
hashCode
in interfaceListenerHook.ListenerInfo
- Overrides:
hashCode
in classObject
- Returns:
- The hash code of this
ListenerInfo
.
