Which is sort of what I described, except I would probably define in the derived class the CONST version, and make the non-const version forward to it, since that is always well defined. If the const version is called on an actual const object, and then it const-casts to the non-const version, and that ends up actually not being actually const, then you have invoked undefined behavior. As I was pointing out, if you end up in this situation, your really need to evaluate why you got there, as something seems off. |
