Return the arguments for the request.

CORBA::ContextList_ptr CORBA::Request::contexts ( void ) [inline]

Return a list of the request's result's contexts. Since TAO does not implement Contexts, this will always be 0.

void CORBA::Request::ctx ( CORBA::Context_ptr ctx ) [inline]

void CORBA::Request::get_response ( void )

void CORBA::Request::handle_response	(	TAO_InputCDR &	incoming,
		GIOP::ReplyStatusType	reply_status
	)

Callback method for deferred synchronous requests.

void CORBA::Request::invoke ( void )

Perform method resolution and invoke an appropriate method.

If the method returns successfully, its result is placed in the result argument specified on create_request. The behavior is undefined if this Request has already been used with a previous call to invoke>, send>, or .
