CRTP (Mixins)
Learn how CRTP can be used to implement mixins in C++.
We'll cover the following...
Mixins
Mixins are a class with methods that can be used by classes even if they’re not derived from them. It’s a popular idea when designing classes to mix in new code. Therefore, it’s a technique often used in Python to change the behavior of a class by using multiple inheritances. In contrast to C++, it’s legal in Python to have more than one definition of a method in a class hierarchy. Python simply uses the method that’s first in the Method Resolution Order (MRO).
