Method Detail

_invoke

public OutputStream _invoke(String _method,
                            InputStream _is,
                            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.

_is - 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
