Thank you for your clarification.
I just didn't know the fact that ref type member var's could be assigned using '=' before you told me.
It sounds like you'd be assigning the underlying variable the references were initialized with, but you want is to make the reference point at a different variable?
Your are right and it's my fault. I should have had a trial-and-test before posting a reply. :-( To make it clearer, I'm finding something like this: class Foo { int & i_; Foo& operator=(const Foo& rhs) { if(&rhs == this) return *this; i_ = rhs.i_; return *this; } } this is not accepted by my VC9 compiler.
However, I'm also curious on the question you raised for me: :-)
Is it possible to make a class which has reference type members default constructible?
AFAIK, the answer is no. I hope and don't hope there's a different answer.
It sounds like you need to be using pointers instead of references.
Yes, it seems to be the only way, as far as I don't to make thing more complex by using another layer of indirectness. Thanks for your time B/Rgds Max
