a class inside a class

x · 2003-01-28T18:43:55

class A { class B { }; }; What does that mean? class B belongs to class A. Can you please provide a practical example of this (game-development wise)? I think I understand the concept, but I still don''t understand why as opposed to: class B { }; class A { B something; }; return 0;

Edit: hold on, you didn''t mean that, did you? You can do this:

Oops, looks like my fingers and my mind spoke different language. This was what I mean: Does B exist in C when C inherit A considering B is protected/public? If so, can I overload B within the namespace of C without declaring a new class (class D, in dalleboy''s example).

  class A{public:    class B    {        int foo;    };};class C : public A{    class B   // overloaded B    {        int newfoo;    };};

return 0;

As to where or why you use this particular technique; it''s used all over the STL(e.g.list::iterator)
