      public boolean matches(Object otherEvent)
      Description copied from interface: Event
      Compares two events to see if they match, meaning that a listener that registered to receive notifications like referenceEvent will be notified of any occuring event for which referenceEvent.matches(occuringEvent) will return true. The matching algorithm depends on the event implementation. For example for Document events two events match if they implement the same event class and if their EventFilter match. Note that the implementation is left open in order to cater for all the possible ways this Observation component can be used.
      Specified by:
      matches in interface Event
      Parameters:
      otherEvent - the occuring event matched against the current object
      Returns:
      true if the passed event matches this event, false otherwise.
