How to do this for my example classes, is it doable ? class A { public: virtual ~A(); virtual void foo(); }; class B : public A { public: virtual ~B(); virtual void foo(); }; class C : public B { public: virtual ~C(); ...
What's the purpose of this pattern? What is it called? It looked very strange when I saw it the first time, though I have now seen it many times. template<typename Derived> struct Base { //... }; struct Example : Base<Example> { //... }; ...
