I'm on-line therefore I am. JimmyRopesI 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.

A class that does little or no real work itself, instead passing requests off onto one or more other classes / APIs.

A taco class? Wouldn't "adapter class" be the same?

Something similar to what my definition of a Taco Shell would be. You don't really need to know about what's inside it from the shell you can tell it's a taco. Just know that it's going to be amazing and the flavor will be unreal. At least for the taco's at our house.

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.

Well, it is nice when it works out that way... ;)

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 :)

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'.
