    • _invoke

      public OutputStream _invoke(String $method, InputStream in, ResponseHandler $rh)
      Description copied from interface: InvokeHandler
      Invoked by the ORB to dispatch a request to the servant. ORB passes the method name, an InputStream containing the marshalled arguments, and a ResponseHandler which the servant uses to construct a proper reply. Only CORBA SystemException may be thrown by this method. The method must return an OutputStream created by the ResponseHandler which contains the marshalled reply. A servant must not retain a reference to the ResponseHandler beyond the lifetime of a method invocation. Servant behaviour is defined as follows:

      1. Determine correct method, and unmarshal parameters from InputStream.

      2. Invoke method implementation.

      3. If no user exception, create a normal reply using ResponseHandler.

      4. If user exception occurred, create exception reply using ResponseHandler.

      5. Marshal reply into OutputStream returned by ResponseHandler.

      6. Return OutputStream to ORB.

      Specified by:
      _invoke in interface InvokeHandler
      Parameters:
      $method - The method name.
      in - The InputStream containing the marshalled arguments.
      $rh - The ResponseHandler which the servant uses to construct a proper reply
      Returns:
      The OutputStream created by the ResponseHandler which contains the marshalled reply
