How to automatically register a class on creation

http://stackoverflow.com/questions/10332725/how-to-automatically-register-a-class-on-creation

to automatically register a class on creation I was wondering whether a design pattern.. whether a design pattern or idiom exists to automatically register a class type. Or simpler can I force a method to get called.. static std vector std string names static void registerAnimal std string name if not already registered names.push_back..

Getting a new instance. Another idea is to have the types register themself in base.hpp template typename T Base createT return.. class DerivedB ... private static DerivedRegister DerivedB reg in derivedb.cpp DerivedRegister DerivedB DerivedB reg DerivedB.. reg in derivedb.cpp DerivedRegister DerivedB DerivedB reg DerivedB You could decide to create a macro for the registration..
