Summary

In this chapter, we have advanced our pursuit to become better C++ programmers through widening our knowledge of design patterns. We have explored the Adapter pattern in both the concept and through multiple implementations. Our first implementation used private inheritance two derive the Adapter from the Adaptee class. We specified our Adapter as an abstract class and then used public inheritance to introduce several Target classes based on the interface provided by our Adapter class. Our second implementation instead modeled the relationship between the Adapter and Adaptee using association. We then looked at an example usage of an Adapter as a wrapper to simply add an OO interface to existing function-based application components.

Utilizing common design patterns, such as the Adapter pattern, will help you more easily reuse existing, well-tested portions of code in a manner understood by other programmers. By utilizing core design patterns, you will be contributing to...
