UpdatableCRTP< Derived > Class Template Reference

#include <AH/Containers/Updatable.hpp>

Detailed Description

template<class Derived>
class UpdatableCRTP< Derived >

A super class for object that have to be updated regularly.

All instances of this class are kept in a linked list, so it's easy to iterate over all of them to update them.

This version uses static polymorphism using the Curiously Recurring Template Pattern. This requires less virtual function calls.
(Only the destructor is virtual.)
