Implementing The Servant (Cont.)

And the class's implementation follows:

// constructor - note that we need to use the _duplicate
// method to make sure the poa's reference count is
// increased. Forgetting this duplication might cause odd
// runtime failures. Had we used a '_var' variable - that
// wouldn't be necessary.
HelloWorldImpl::HelloWorldImpl(PortableServer::POA_ptr poa)
  : myPoa (PortableServer::POA::_duplicate (poa))
{
}

// write a "hello world" message to the screen.
void
HelloWorldImpl::sayHello()
{
    cout << "Hello World" << endl << flush;
}
