Overview of this book

C++ is a general-purpose programming language designed for efficiency, performance, and flexibility. Design patterns are commonly accepted solutions to well-recognized design problems. In essence, they are a library of reusable components, only for software architecture, and not for a concrete implementation. This book helps you focus on the design patterns that naturally adapt to your needs, and on the patterns that uniquely benefit from the features of C++. Armed with the knowledge of these patterns, you’ll spend less time searching for solutions to common problems and tackle challenges with the solutions developed from experience. You’ll also explore that design patterns are a concise and efficient way to communicate, as patterns are a familiar and recognizable solution to a specific problem and can convey a considerable amount of information with a single line of code. By the end of this book, you’ll have a deep understanding of how to use design patterns to write maintainable, robust, and reusable software.

Adapters and Decorators

This chapter takes on two classic patterns in object-oriented programming (OOP) - the Adapter pattern and the decorator pattern. These patterns are just two of the original twenty-three design patterns that were introduced in the Design Patterns – Elements of Reusable Object-Oriented Software book by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides. As an object-oriented language, C++ can take advantage of these patterns as well as any other language. But, as is often the case, generic programming brings some advantages, variations, and, with it, new challenges to the classic patterns.

The following topics are covered in this chapter:

  • What are the adapter and decorator patterns?
  • What is the difference between the two?
  • What design problems can be solved by these patterns?
  • How are these patterns used in C++?
  • How does generic programming help to design adapters and decorators?
  • What other, different, patterns offer...
