AnimNode To C++

I want use C++ to apply Character anim,but I found no tutorials on AnimNode.So,Can you help me write a simple process about the pictures?

Anim nodes can only be done in blueprint as far as I know, just like material blueprints they do not really represent functions or something that could be clearly translated into code, and since any code would have to be heavily reinterpreted by the engine it doesn’t make much sense to not simply use the simplest and most intuitive way of doing things (i.e. in blueprint)
