Implementing the Callback Object (SAP Library

Implementing the Callback Object

Use

Use the Notificator_impl.cpp file that you have generated in the Generating C++ Code for the Notificator Object step of this tutorial to provide an implementation of the message method of the callback object.

Procedure

...

1. Open the Notificator_impl.cpp file for editing.

2. Enter the following code in the body of the message method:

void

examples::iiop::Notificator_impl::message(::CORBA::WStringValue* arg0)

throw(CORBA::SystemException)

{

cout << endl << "Notificator: ";

const CORBA::WChar* w = arg0->_boxed_in();

while(*w != 0)

cout << (char)(*w++);

cout << endl;

}

Result

You now have a fully-functional implementation of the Notificator callback object.

The full source code of the Notificator_impl.cpp file must be:
