C++ 如何用不同的名字呼叫一个Function？

Question

In c++, I want to want to make a wrapper class. I am using a math library called glm. There are classes in there called glm::mat4 for matrix math and glm::vec3 for vector math. What I want to do is make a class called Vector which can do everything glm::vec3 can.

The problem is, lets say I want to create a wrapper or extra layer over glm::vec3, for my Vector class I would have to rewrite all the functions of vec3 and then inside those function I call the glm::vec3 functions (sort of how any wrapper would work).

So my question is there a way to avoid this cumbersome work? Is there a way I can use the glm::vec3 as it is but just call Vector instead (name change)? Is this even possible???

Answer 1

You can alias your type like this:

namespace glm {

class vec3 {
// your implementation...
};

} // namespace glm

// create an alias for glm::vec3
using Vector = glm::vec3;

And after, using Vector will be just like using glm::vec3
