How to store TypeInfo

Question

  class A {}
  A a;
  type_info info = typeid (a); // error type_info is private

i want a list list<type_info> to store the type of classes. Is there a solution?

Answer 1

You can't create copies of 'type_info' objects. However, the result if 'typeid' is an Lvalue and the corresponding 'type_info' objects, once obtained, continue to live till the end of the program. For these reasons, you can safely store pointers to 'type_info' objects in your list.

Answer 2

You cannot instantiate objects of the type_info class directly, because the class has only a private copy constructor. Since the list needs copy constructor...

If you really need it, use std::list< type_info*>.

I don't know why you need this list, but I would think to an alternative design, not involving RTTI, if possible.
