Hands-On Design Patterns with C++

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.

SFINAE, Concepts, and Overload Resolution Management

The idiom we study in this chapter, Substitution Failure Is Not An Error (SFINAE), is one of the more complex in terms of the language features it uses. Thus, it tends to get inordinate amounts of attention from C++ programmers. There is something in this feature that appeals to the mindset of a typical C++ programmer - a normal person thinks that, if it isn’t broken, don’t mess with it. A programmer, especially one writing in C++, tends to think that, if it isn’t broken, you’re not using it to its full potential. Let’s just say that SFINAE has a lot of potential.

We will cover the following topics in this chapter:

  • What are function overloading and overload resolution? What are type deduction and substitution?
  • What is SFINAE, and why was it necessary in C++?
  • How can SFINAE be used to write insanely complex, and sometimes useful, programs?
