Adapter in C++
Adapter is a structural design pattern, which allows incompatible objects to collaborate.
The Adapter acts as a wrapper between two objects. It catches calls for one object and transforms them to format and interface recognizable by the second object.
Usage of the pattern in C++
Usage examples: The Adapter pattern is pretty common in C++ code. It’s very often used in systems based on some legacy code. In such cases, Adapters make legacy code work with modern classes.
Identification: Adapter is recognizable by a constructor which takes an instance of a different abstract/interface type. When the adapter receives a call to any of its methods, it translates parameters to the appropriate format and then directs the call to one or several methods of the wrapped object.
