move/copy constructors combination of multiple parameters

Let's say I got a class which takes two parameters when constructing. And I need to deal with the rvalue/lvale, does that mean I should write 4 constructors?

class Test {
 public:
  Test(const A& a, const B& b) {}
  Test(const A& a, B&& b) {}
  Test(A&& a, const B& b) {}
  Test(A&& a, B&& b) {}
};

Is there any way I can do this easier? Or is this design pattern wrong?

What do you do with the parameters? Are you copying/moving them to member variables? – HolyBlackCat Mar 08 '19 at 12:29
