Visitor Pattern in Real Applications

Are you tired of polluting your domain objects with auxiliary business logic? Do you struggle to add new features to a complex object structure without triggering a cascade of class modifications?

The Visitor Pattern is the elegant, time-tested solution to this problem, yet its true power is often confined to textbook examples.

This book moves beyond the ubiquitous 'Shape' and 'Car Element' analogies to provide a deep, practical look at how the Visitor Pattern is successfully deployed in industrial-strength software. You will learn the why, when, and how of implementing Double Dispatch to achieve unmatched Separation of Concerns and adhere to the Open/Closed Principle.

Examples in this book are in the java programming language.
