Hands-On Design Patterns with C++ (Second Edition) - Second Edition

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.

Summary

Yet again, we have seen the power of C++ to essentially create a new language out of the existing one; C++ does not have named function arguments, only positional ones. That is part of the core language. And yet, we were able to extend the language and add support for named arguments in a reasonable-looking way, using the method chaining technique. We have also explored the other applications of method chaining beyond the named arguments idiom.

One of these applications, the fluent builder, is again an exercise in creating new languages: the power of the fluent interface, in general, is that it can be used to create domain-specific languages to execute sequences of instructions on some data. And so the fluent builder can be used to allow the programmer to describe the construction of objects as a sequence of steps that are familiar in a particular domain. Then, of course, there is the implicit builder that (with the right indents) even makes C++ code look a bit like the...
