std::vector that holds class methods

Question

I have done this to enumerate my class members

enum MemberType {A, B, C, D};

class Hello
{
public:
    std::vector<std::function<void(Hello*, void)>>     m_members;

    void func()
    {
    };

    Hello()
    {
        m_members[A] = func();
    }
};

What is wrong here?

Answer 1

First, you had an extra void:

std::vector<std::function<void(Hello*)>>     m_members;

Then, you need to assign something more like this:

m_members[A] = &Hello::func;

Or you can store bound functions, in which case std::function<void()> and std::bind(&Hello::func, this).
