All Implemented Interfaces:
ListenerHook.ListenerInfo

public class ListenerInfo extends Object implements ListenerHook.ListenerInfo
  • Constructor Details

  • Method Details

    • getBundle

      public Bundle getBundle()
    • getBundleContext

      public BundleContext getBundleContext()
      Description copied from interface: ListenerHook.ListenerInfo
      Return the context of the bundle which added the listener.
      Specified by:
      getBundleContext in interface ListenerHook.ListenerInfo
      Returns:
      The context of the bundle which added the listener.
    • getListenerClass

      public Class getListenerClass()
    • getListener

      public EventListener getListener()
    • getParsedFilter

      public Filter getParsedFilter()
    • getFilter

      public String getFilter()
      Description copied from interface: ListenerHook.ListenerInfo
      Return the filter string with which the listener was added.
      Specified by:
      getFilter in interface ListenerHook.ListenerInfo
      Returns:
      The filter string with which the listener was added. This may be null if the listener was added without a filter.
    • getSecurityContext

      public Object 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 return 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.

      Specified by:
      isRemoved in interface ListenerHook.ListenerInfo
      Returns:
      false if the listener has not been been removed, true otherwise.
    • equals

      public boolean equals(Object obj)
      Description copied from interface: ListenerHook.ListenerInfo
      Compares this 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.
      Specified by:
      equals in interface ListenerHook.ListenerInfo
      Overrides:
      equals in class Object
      Parameters:
      obj - The object to compare against this ListenerInfo.
      Returns:
      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.
    • hashCode

      public int hashCode()
      Description copied from interface: ListenerHook.ListenerInfo
      Returns the hash code for this ListenerInfo.
      Specified by:
      hashCode in interface ListenerHook.ListenerInfo
      Overrides:
      hashCode in class Object
      Returns:
      The hash code of this ListenerInfo.
