  • Method Details

    • getListenerList

      public Object[] getListenerList()
      Passes back the event listener list as an array of listener type, listener pairs. Note that for performance reasons, this implementation passes back the actual data structure in which the listener data is stored internally. This method is guaranteed to pass back a non-null array, so that no null-checking is required in fire methods. A zero-length array of Object is returned if there are currently no listeners.

      Absolutely no modification of the data contained in this array should be made. If any such manipulation is necessary, it should be done on a copy of the array returned rather than the array itself.

      Returns:
      an array of listener type, listener pairs.
