Question

I’m trying to have method void run( string method ) which would run method in that class. For example:

class Foo {
    public:
    void run( string method ) {
        // this method calls method *method* from this class
    }
    void bar() {
        printf( "Function bar\n" );
    }
    void foo2() {
        printf( "Function foo2\n" );
    }
}

Foo foo;

int main( void ) {
    foo.run( "bar" );
    foo.run( "foo2" );
}

this would print:

Function bar
Function foo2

Thanks! 🙂

You can create an std::map which maps strings to member function pointers, as long as all the functions you want to call have the same signature.

The map would be declared like:

 std::map<std::string, void(Foo::*)()> function_map;
