Prevent a virtual function bering overloaded twice in a sub-sub-class

Question

I have a base class Base, a somewhat more specialized class SpecializedBase derived from Base, and subclasses of the latter such as Derived.

I implement a virtual function in SpecialisedBase which is pure virtual in Base. How to be sure that this function is not overloaded in Derived?

yes, if you can use C++11, you can write your class like

    struct derived {
        virtual void f() final;
    };

but wait, there's more: you can even put `final` after the class name and prevent the entire class from being inherited from. – TemplateRex Sep 24 '13 at 14:35
