Practical Object-Oriented Design: An Agile Primer Using Ruby, 2nd Edition

Book Description

The Complete Guide to Maintainable, Manageable, Pleasing, and Powerful 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 , 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 , all downloadable from the companion website, poodr.com. Fully updated for Ruby 2.5, 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.
