Questions tagged [wrapper]
A wrapper is an OOP technique where an object encapsulates (wraps) another object, resource (dynamically allocated memory, OS file/widow handle, socket, thread mutex, etc) or a set of subroutines, hiding/protecting it and providing another (possibly easier to use) interface. When using this tag on implementation heavy questions - tag the code language the implementation is written in.
