Getting class name as a string in static method in C++

Assume we are working with Clang strictly. No other compiler is being used. Also note that Clang supports CXX ABI.

We are using C++14.

Normally, we would get demangled class name like so:

#include <cxxabi.h>

class GoodClass {
public:
    virtual const char *foo() const noexcept;
}

const char *
GoodClass::foo() const noexcept
{
    //  Naive implementation, not gonna' check any errors and stuff.
    int32_t status = 0;

    return abi::__cxa_demangle(typeid(*this).name(), 0, 0, &status);
}

This method will help us when we need class names of public subclasses of this class:

class SomeSubclassOfGoodClass : public GoodClass { }

SomeSubclassOfGoodClass object;
std::cout << object.foo(); //  prints "SomeSubclassOfGoodClass"

However, in static methods, we could not use this since there is no instance. Therefore, it is impossible to serve an object to the typeid directive.

The examplary method serves well (with polymorphism), however it needs an instance to operate. This would involve problems about OO (such as constructors).

What would you do in a situation like this?

Thank you for your attention.
