Question

It’s possible to overload the not operator for a class:

class TestA
{
    public:
       bool Test;
       const bool operator!(){return !Test;}
};

So that…

TestA A; A.Test = false;
if(!TestA){ //etc }

…can work. However, how does the following work?

if(TestA) //Does this have to be overloaded too, or is it the not operator inverted?

I will add, having read it, I am slightly confused by the typedef solution that is employed, and I don’t fully understand what is occurring, as it seems somewhat obsfucated. Could someone break it down into an understandable format for me?

Answer 1

You could write an operator bool(). This takes care of coercion to bool, making statements as your above one possible.
