pointer to diferent member functions
Author
Is it possible , to make a pointer that can point to different member functions ?
I know that I can create a pointer to a member function like that :
But if for example I have 2 different classes and I wan't to make a pointer that can point to any member function in these classes. Can it be done ?
Thanks for any input.
C++ doesn't natively support that kind of pointer. You may want to consider a functor implementation instead such as boost::function.
