Virtual Inheritance?

[Paolo F Cantoni]

OK, I surrender!

There's a checkbox on the Generalization Properties General Tab marked Virtual Inheritance.

There's no mention of it in the documentation, and it doesn't appear to be UML 2.

However, its name seems intriguingly close to a functionality I'd love to see in modelling tools.

Can anyone enlighten me?

Virtual Inheritance is a C++ technique for dealing with multiple instances of inherited base classes. I think Bruce put up a link a few months ago...

...ah, here it is! http://cplus.about.com/od/beginnerctutorial/l/aa121502a.htm (thanks Bruce)

Thanks,

I now realise what I'm really after is derived (not virtual) inheritance.

After I fired off the post, I remembered that it was a C++ concept - but not its rationale.
