What would your definition of a wrapper class be.

I'd say that a wrapper class presents a proxy to some other class or API that may be at a lower level of abstraction or may be from a different framework. But then I've always sucked at defining things clearly :)

I dont know.. I'm asking you. Or maybe your sense of humour has eluded me.

the second part was meant seriously. In my eyes, there's no difference between "wraapper" and "adapter" class, though use differs a little bit. Basically, a wrapper class puts a different interface around an implementation. This could be an OO Wrapper for a procedural file API (like MFC's CFile), or a class implementing the IStream on top of CFile. The first is almost always called "wrapper" class, for the second, "adapter" is more common.

Putting together a few of the responses--most classes are like taco filling. Lettuce, meat, cheese, and at all doesn't hold together very well. A wrapper class, like a taco shell, doesn't do much itself, it just makes it easy to hold together all the rest of the stuff. ;P Marc

I'd have to describe a wrapper class as a module that hides something ugly and useless - like MFC Comms, TAPI, and MAPI - behind a friendly, usable facade, like cModem, cPBX or cPostOffice. A wrapper probably should not only make something usable, but also shield a non-expert user from self-inflicted wounds arising from misunderstood or undocumented functions while trying to use the useless. Either that, or it's a taco of some kind. Or maybe a course at McDonalds U on neatly packaging toxic waste 'to go'.

How can you tell I changed it? I didn't know you had moderator powers??? :vegemite::-D

Yeah, that's a good definition. I tend to think of wrapper classes as providing a higher level of abstraction to the outside world so that the underlying API that they're "wrapping" is easier to use.

I don't think so. I'm not asking how to accomplish a certain programming task. It's actually a second opinion I'm looking for. A friend of mine asked me my defintion of a wrapper class was. I gave her my opinion, and offered to post the a question on codeproject to see what you guys/gals come up with.
