WebApr 15, 2016 · This does indeed introduce the overhead of dynamic dispatch (which you were probably trying to avoid by using CRTP), but dynamic dispatch is the only way to get runtime polymorphism in C++. It can still be beneficial, though.

You can learn all about it in the series on CRTP on Fluent C++. We will use it to declare methods with the correct derived prototypes in the CRTP base class, methods that will then be injected through inheritance into the derived class itself:
