Using generic std::function objects with member functions in one class

Question

For one class I want to store some function pointers to member functions of the same class in one map storing std::function objects. But I fail rig

Answer 1

Either you need

std::function f = &Foo::doSomething;

so that you can call it on any instance, or you need to bind a specific instance, for example this

std::function f = std::bind(&Foo::doSomething, this);
