    A functor is a class that acts like a function. It overloads the function call operator:

    Code:
    class ZCharacterManagerFindHookFunctor {
        MUID muid_;
        public:
        ZCharacterManagerFindHookFunctor(MUID m)
        {
            muid_ = m;
        }
    
        void operator()() {
            ZCharacterManagerFindHook(muid_);
        }
    };
    
    void func(ZCharacterManagerFindHookFunctor& f)
    {
        // Invoke the functor
        f();
    }
    int main()
    {
        MUID m;
        ZCharacterManagerFindHookFunctor f(m);
    
        // Pass the functor to a function, or store it in a data structure,
        // or whatever
        func(f);
    
        return 0;
    }
    The crows maintain that a single crow could destroy the heavens. Doubtless this is so. But it proves nothing against the heavens, for the heavens signify simply: the impossibility of crows.
