Question

I would like a class B not to be able to redefine one of the member function of its base class A. Is there a way to do that?

EDIT:

Thanks for the answers. Can I prevent non-virtual member functions from being overridden as well?

Answer 1

If your methods are virtual, in C++11 you can prevent overriding them with final.

class A
{
public:
   virtual void foo() final;
};

class B : public A
{
public:
   void foo(); // <-- error
};

You can’t prevent hiding.
