Hi, I've been looking through the boost library and I haven't been able to find anything that works like typeid() that returns the exact (i.e. derived) class name instead of just the base class.
I know this is going to seem nitpicky, but it affects my ability to know how to help you: typeid doesn't return names; it returns type_info objects.
I want to compare two derived classes to make sure that they are of the same class, but typeid() only returns the name of the base class.
If you have two classes, A and B, you can just use boost::is_same<A,B>::value. But I don't think that's what you mean. I assume you mean that you want to compare the type of two objects x and y to which you hold base class pointers or references? If the objects' classes are polymorphic, template <class A, class B> bool same_derived_class(A const& a, B const& b) { return typeid(a) == typeid(b); }; should work, with no additional help from a Boost library... ...which makes me very confused about what you're trying to achieve. -- Dave Abrahams Boost Consulting www.boost-consulting.com
