Thread: Wrapper classes

Fortunately for you, college doesn't teach commercially-viable programming skills.

The coding world is just packed full of wrappers!
A wrapper is something that makes something else easier to deal with, though there's usually nothing stopping you from just using that other thing directly. They also don't add any functionality beyond the thing they're wrapping. In fact they often expose a reduced set of functionality, jsut to make the underlying thing they're wrapping easier to deal with.
They can wrap another class, or a bunch of classes, or just a bunch of free functions that perhaps belong to some kind of API.

For example, Much of libraries like MFC can be considered to be a bunch of wrappers. A CWindow is really just a wrapper around the HWND data type, plus much of the functionality of the Win32 API made conveniently available as member functions.
