Java LocalClientRequestDispatcher.useLocalInvocation方法代码示例

/**
 * The <tt>isLocal</tt> method has the same semantics as the
 * ObjectImpl._is_local method, except that it can throw a RemoteException.
 * (no it doesn't but the spec says it should.)
 *
 * The <tt>_is_local()</tt> method is provided so that stubs may determine
 * if a particular object is implemented by a local servant and hence local
 * invocation APIs may be used.
 *
 * @param stub the stub to test.
 *
 * @return The <tt>_is_local()</tt> method returns true if
 * the servant incarnating the object is located in the same process as
 * the stub and they both share the same ORB instance.  The <tt>_is_local()</tt>
 * method returns false otherwise. The default behavior of <tt>_is_local()</tt> is
 * to return false.
 *
 * @throws RemoteException The Java to IDL specification does to
 * specify the conditions that cause a RemoteException to be thrown.
