Container for pointers to member functions with different arguments

Question

I am looking everywhere (Modern C++ design & co) but I can\'t find a nice way to store a set of callbacks that accept different arguments and operate on different classe

Answer 1

Use std::function to store the calls and then use a variadic template argument to forward and bind the function parameters:

class Clock
{
    vector> tasks;

    template
    void defer(F f, Args&&... args)
    {
        tasks.push_back(bind(f, forward(args)...);
    }

}

void f(A a, B b);

int main()
{
    A a;
    B b;

    Clock c;
    c.push_back(f, a, b);
}
