Hands-On Design Patterns with C++

Summary

We have studied two of the most commonly used patterns—not just in C++, but in software design in general. The Adapter pattern offers an approach to solving a wide class of design challenges. These challenges have only the most general property in common—given a class, a function, or a software component that provides certain functionality, we must solve a particular problem, and build a solution for a different, related problem. The decorator pattern is, in many ways, a subset of the Adapter pattern, which is restricted to augmenting the existing interface of the class of a function with new behavior.

We have seen that the interface conversion and modification done by the adapters and decorators can be applied to interfaces at every ...
