“context was in articles about OOD, and it was said something like it is good practice to plan your classes in the way that for changing some aspect of program it will be enough to write new class, register it and you get new staff”
Now it seems to me you are talking about the publisher/subscriber pattern. It allows loose coupling between caller and callee.
You can find a C++ implementation everywhere, in the GoF book, or here:
