Question

My intention is to refrain from macros style when I need to define a lot of similar methods. So I’m interested, can I use templates or anything like that?

This is the general idea in pseudo-c++:

template <class T, class U> void myMethod(T t, U u){ ..do a lot .. }

class A {
public:
  A(){}
  void myMethod<int, int>;
  void myMethod<float, char>;

  // ... etc
};

Answer 1

template <class T, class U> class A 
{
public:
    void MemberSet( T t, U u );
};

ADDED:

#include <typeinfo>
#include <iostream>

using namespace std;
class A 
{
public:
    template <class T, class U> void MemberSet( T t, U u ) {
        cout << typeid(t).name() << " " << typeid(u).name() << endl;
    };
};

int main() 
{
    A a;
    a.MemberSet(5,5);
    a.MemberSet<char, long>(5,5);
}

you may want to explicitly instantiate

template void A::MemberSet<int, long> (int, long);
