Title: Design Patterns in Modern C++ – Reusable Approaches for Object-Oriented Software Design<\/strong><\/em><\/p>\n

Author: Dmitri Nesteruk<\/strong><\/em><\/p>\n

Publisher: Apress<\/strong><\/em><\/p>\n

Year: 2018<\/strong><\/em><\/p>\n

Luck has been on my side for the past few weeks; I have been getting access to nice books to read. I wrote about The<\/strong><\/em>\u00a0Modern C++ Challenge<\/strong><\/em><\/a> in my last post. Today, I am going to review another nice book.<\/p>\n

Since the original GoF book<\/a><\/strong><\/em>, much has been written and talked about Design Patterns<\/strong><\/em>. They are the bread and butter of every serious software developer. The C++ examples given in the GoF<\/strong><\/em> book are somewhat outdated now because the language itself has evolved significantly over this long period. So it is refreshing to see a book that focusses entirely on Design Patterns<\/strong><\/em> using the latest C++ standard.<\/p>\n

The presentation format of the various design patterns is different in this book compared to the original GoF<\/strong><\/em> book. In the latter, each pattern is explained using various sections such as Intent<\/strong><\/em>, Motivation<\/strong><\/em>, Applicability<\/strong><\/em>, and so on. In this book, however, that template is not followed. It is somewhat of a linear presentation with several examples. I find this acceptable because the book\u2019s purpose is not to teach design patterns, but to present the classic patterns in the context of the current C++ standard. What this means is that if you are new to design patterns, then you are better off starting with the GoF<\/strong><\/em> book and then coming back to this book for the specifics of C++ implementation. I doubt if anyone can do better than the GoF<\/strong><\/em> book in terms of explaining the concepts.<\/p>\n

One thing I like about this book is that the author describes important C++ concepts (e.g. Curiously Recurring Template Pattern<\/strong><\/em><\/a>) and also the SOLID<\/strong><\/em><\/a> design principles in the first chapter, before describing the actual patterns. This is very helpful since it lays the foundation for the following chapters.The author also warns us that adopting certain patterns (e.g. Observer<\/strong><\/em>) might sometimes result in overengineering<\/strong><\/em>. I couldn’t agree more! One has to understand the various design patterns and apply them judiciously while implementing real-world projects.<\/p>\n

All the patterns described in the GoF<\/strong><\/em> are covered in this book as well, and more or less, in the same order.\u00a0<\/span><\/p>\n

1. Creational Patterns:<\/strong><\/h3>\n

– Builder<\/p>\n

– Factories (Abstract factory and Factory Method)<\/p>\n

– Prototype<\/p>\n

– Singleton<\/p>\n

2. Structural Patterns:<\/strong><\/h3>\n

– Adapter<\/p>\n

– Bridge<\/p>\n

– Composite<\/p>\n

– Decorator<\/p>\n

– Facade<\/p>\n

– Flyweight<\/p>\n

– Proxy<\/p>\n

3. Behavioral Patterns:<\/strong><\/h3>\n

– Chain of Responsibility<\/p>\n

– Command<\/p>\n

– Interpreter<\/p>\n

– Iterator<\/p>\n

– Mediator<\/p>\n

– Memento<\/p>\n

– Null Object\u00a0<\/span><\/p>\n

– Observer<\/p>\n

– State<\/p>\n

– Strategy<\/p>\n

– Template Method<\/p>\n

– Visitor<\/p>\n

The Null Object<\/strong><\/em> pattern under Behaviour Patterns<\/strong><\/em> was not described in the GoF<\/strong><\/em> book, but subsequently appeared in Pattern Languages of Program Design, Volume 3<\/strong><\/em><\/a>.\u00a0<\/span><\/p>\n

A nice bonus is the discussion on Maybe Monad<\/strong><\/em> in the Appendix. Monads<\/strong><\/em><\/a> are originally from Haskell and there are libraries attempting to support them in other languages such as Python<\/strong><\/em>, Ruby<\/strong><\/em> and Lisp<\/strong><\/em>. It is interesting to learn about it from C++ point of view.\u00a0<\/span><\/p>\n

I must say I thoroughly enjoyed reading this book and I recommend it highly. If you are a serious C++ developer, just go and buy it!<\/p>\n

I found two interesting sites that discuss C++ Design Patterns<\/strong><\/em>. See this<\/strong><\/em><\/a>\u00a0and this<\/strong><\/em><\/a>.<\/p>\n

(P.S. I am also reading a couple of other good books on C++ Concurrency<\/strong><\/em> and Designing DSLs<\/strong><\/em>. So don\u2019t be surprised if I continue with book reviews in the next few posts as well!)<\/p>\n

Have a great weekend!<\/p>\n","protected":false},"excerpt":{"rendered":"
