I always wondered about something related. Assuming at some Point you Need to know what class an object actually is of. Then, as far as I understand, I could try dynamic_cast<> to all possible classes. And that's O(n), if n is the number of possible classes. So having a map or hashtable to just look it up should theoretically be faster for large enough n. Is this correct or am I missing a possible way to use dynamic_cast<> efficiently for this?
