Learn when and how to use Clojure's polymorphic features to develop efficient multithreaded applications

Key Features

Get to grips with the different polymorphic tools that Clojure offers
Develop a taste for good Clojure designs through various engaging examples
Study various design principles and learn ways to use them in your applications

Book Description

Clojure is a modern, dynamic language that you can use to develop robust, multithreaded programs. Clojure Polymorphism is a comprehensive guide that shows you how to use Clojure's features to your advantage.

The book begins by describing examples that show how to define and implement abstractions with plain functions and multimethods. Then you'll analyze these examples and separate the good and bad aspects of their design principles. You'll also learn how to perform data transformation abstraction with a plain function and discover how to write new cross-platform predicates while keeping the core of your abstraction free from reader conditionals. The later chapters explain the considerations to keep in mind when implementing Clojure protocols on the Java Virtual Machine (JVM).

By the end of this book, you'll know how to use the various polymorphic tools of Clojure to your advantage while designing your applications.

What you will learn

Who this book is for

Clojure Polymorphism is useful for all programmers who want to leverage Clojure's polymorphic tools to build efficient applications. To get the most out of this book, you must be a moderately proficient Clojure programmer.
