  36 /**     Wrapper base class for UNO services which emulates the upcoming
  37      mode of automatic runtime Java classes to get rid of the need for
  38     queryInterface.
  39
  40     Because its not worth the efford to create a runtime generated wrapper
  41     for this purpose, as it might be for OOo 2.0, you still have to use
  42     UnoRuntime.queryInterface() for interfaces which are optional or come
  43     from a subclass.  But for non optional interfaces you can already
  44     directly call their methods.
  45
  46     This wrapper will only work for UNO objects via a bridge, not for
  47     direct Java objects.
