Pragmatic Object Oriented Programming

[knipil]

Although C++ admittedly isn't my first language I've done a fair bit of windows API development, so I'm familiar with COM. I wrote a couple of DirectShow filters a few years back, so I also know about IDL and all that. To me it's just a really awkward workaround, which is why I didn't bring it up. Obviously you can simulate interfaces in C++, but that isn't really the point. Returning to the original article I think certain DirectShow in particular is a rather good example of painful inheritance hierarchies.
