Passing Pointers from a Class?

[Fasine]

This may not exactly be a beginner question, but can anyone tell me how to pass a pointer to the calling class as a parameter in a function? I know that Java has a this.* command to allow an object to access itself, but I don't know how to do this in C++. I could always pass in the pointer when creating the class, but that's inconvenient and it must be available to the class without me doing that.

/*The function I'm calling. Accepts pointers to two HasPosition class instances, then calculates whether they have collided. I need to be able to call this function from within either of those two classes.*/
bool Coll::GetColl(HasPosition* a, HasPosition* b)

Thanks for your time, everyone!

The

this

keyword in C++ is the pointer to the current instance of the object. To get the actual object to use you need the dereference character, say for example:

class MY
{
    public:
        MY(int i):i_(i)
        {
            this->dosomething();
            //or
            (*this).dosomething();
        }
        void dosomething(){}        
    private:
        int i_;
}
