quick question on using this keyword in 'clone' method ..

[2b|!2b==?]

Is this legal ?


MyClass& MyClass::Clone() const
{
//this should invoke the copy ctor ...
//but can I reference an object within itself ?
MyClass* mc = new MyClass(*this);
return *mc ;
};

Seems acceptable. Why?

MyClass& MyClass::Clone() const
{
//this should invoke the copy ctor ...

And it hopefully does.

//but can I reference an object within itself ?

What do you mean by that? Why wouldn't you be able to?
After all, that's what the 'this' is for.

MyClass* mc = new MyClass(*this);
return *mc ;
};

The trailing semicolon here is most likely illegal.

Erm, ill-posed question - sorry guys, I figured it out myself later. I
was getting myself confused about something entirely different - the
class I am using is a lot more "involved" than the trite MyClass I used
in the example - and I ended up getting myself confused. I think its
time I called it a day - been behind this screen for too long ...

It definitely sounds like it (now that you've mentioned your
position in relation to that screen -- I usually spend my days
*in front* of mine) <g>
