 Implementing the Callback ObjectLocate this document in the navigation structure

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:

#include <Notificator_impl.h>
 
#include <iostream.h>

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