41 * Supports delegation for method implementations in {@link Stub}.
42 * A delegate is an instance of a class that implements this
43 * interface and provides a replacement implementation for all the
44 * methods of <code>javax.rmi.CORBA.Stub</code>.  If delegation is
45 * enabled, each stub has an associated delegate.
46 *
47 * Delegates are enabled by providing the delegate's class name as the
48 * value of the
49 * <code>javax.rmi.CORBA.StubClass</code>
50 * system property.
