Clojure for Java Developers

Overview of this book

We have reached a point where machines are not getting much faster, software projects need to be delivered quickly, and high quality in software is more demanding as ever. We need to explore new ways of writing software that helps achieve those goals. Clojure offers a new possibility of writing high quality, multi-core software faster than ever, without having to leave your current platform. Clojure for Java developers aims at unleashing the true potential of the Clojure language to use it in your projects. The book begins with the installation and setup of the Clojure environment before moving on to explore the language in-depth. Get acquainted with its various features such as functional programming, concurrency, etc. with the help of example projects. Additionally, you will also, learn how the tooling works, and how it interacts with the Java environment. By the end of this book, you will have a firm grip on Clojure and its features, and use them effectively to write more robust programs.

Summary


We have checked the core Clojure mechanisms for concurrent programming, as you can see, they feel natural and they build on already existing paradigms, such as immutability. The most important idea is what an identity and value is; we now know that we can have the following values as identifiers:

  • Refs

  • Atoms

  • Agents

We can also get the snapshot of their value with the defer function or the @ shortcut.

If we want to use something a little more primitive, we can use promises or futures.

We have also seen how to use threads, or Pulsar's fibers. Most of Clojure's primitives aren't specific to some concurrency mechanism, so we can use any parallel programming mechanism with any type of Clojure primitive.
