Edit Question
Title
Body
I have a class hierarchy, and each class in it has an exception class, derived in a parallel hierarchy, thus... class Base { }; class Derived : public Base { }; class BaseException : public std::exception { enum {THIS_REASON, THAT_REASON}; }; class DerivedException : public BaseException { // er...what? }; I would like, in the DerivedException class, to extend the enumeration type to include a new value THE_OTHER_REASON, so that the DerivedException class could hold any of the three values. First of all, ought I to want to do this? Does it seem a reasonable practice? If so, how do I go about it? If not, what alternatives would you recommend? EDIT: A possible duplicate has been suggested here , but the suggested solutions are different because that question is for C# and this for C++.
