Practical Object-Oriented Design, ۲nd Edition

Practical Object-Oriented Design: An Agile Primer Using Ruby, ۲nd Edition

by Sandi Metz (Author)
The Complete Guide to Writing Maintainable, Manageable, Pleasing, and Powerful Object-Oriented Applications

Object-oriented programming languages exist to help you create beautiful, straightforward applications that are easy to change and simple to extend. Unfortunately, the world is awash with object-oriented (OO) applications that are difficult to understand and expensive to change. Practical Object-Oriented Design, Second Edition, immerses you in an OO mindset and teaches you powerful, real-world, object-oriented design techniques with simple and practical examples.

Sandi Metz demonstrates how to build new applications that can “survive success” and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples in the easy-to-understand Ruby programming language, all downloadable from the companion website, poodr.com. Fully updated for Ruby ۲.۵, this guide shows how to

Decide what belongs in a single class
Avoid entangling objects that should be kept separate
Define flexible interfaces among objects
Reduce programming overhead costs with duck typing
Successfully apply inheritance
Build objects via composition
Whatever your previous object-oriented experience, this concise guide will help you achieve the superior outcomes you’re looking for.

Editorial Reviews
Review
Praise for the first edition of Practical Object-Oriented Design in Ruby

“Meticulously pragmatic and exquisitely articulate, Practical Object Oriented Design in Ruby makes otherwise elusive knowledge available to an audience which desperately needs it. The prescriptions are appropriate both as rules for novices and as guidelines for experienced professionals.”

—Katrina Owen, Creator, Exercism

“I do believe this will be the most important Ruby book of ۲۰۱۲. Not only is the book ۱۰۰% on-point, Sandi has an easy writing style with lots of great analogies that drive every point home.”

—Avdi Grimm, author of Exceptional Ruby and Objects on Rails
