/** Wrapper base class for UNO services which emulates the upcoming
     mode of automatic runtime Java classes to get rid of the need for
    queryInterface.

    Because its not worth the efford to create a runtime generated wrapper
    for this purpose, as it might be for OOo 2.0, you still have to use
    UnoRuntime.queryInterface() for interfaces which are optional or come
    from a subclass.  But for non optional interfaces you can already
    directly call their methods.

    This wrapper will only work for UNO objects via a bridge, not for
    direct Java objects.

    @since OOo 2.0.0
