Clojure Polymorphism: Leverage Clojure's Polymorphic Tools to Develop Your Applications
Book information
Description
Learn when and how to use Clojure's polymorphic features to develop efficient multithreaded applicationsKey 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 applicationsBook DescriptionClojure 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* Explore how polymorphism is implemented in Clojure* Discover what design principles to use when creating and implementing abstractions* Explore different ways to implement protocols in Clojure* Implement various design principles while working with the JVM* Write and compare plain functions and multimethods for transforming data * Analyze functions and abstractions for their performance and flexibility* Learn about common "gotchas" to avoid errors when writing codeWho this book is forClojure 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.

Professional Linux kernel architecture ''Wrox programmer to programmer''--Cover. - ''What you are reading right now is the result of an evolution over more than seven years: After two years of writing, the first edition was published in German by Carl Hanser Verlag in 2003. It then described kernel 2.6.0. The test was used as a basis for the low-level design documentation for the EAL4+ security evaluation of Red Hat Enterprise Linux 5, requiring to update it to kernel 2.6.18 (if the EAL acronym does not mean anything to you, then Wikipedia is once more your friend). Hewlett-Packard sponsored the translation into English and has, thankfully, granted the rights to publish the result. Updates to kernel 2.6.24 were then performed specifically for this book''--P. ix
