Presentation: "Clojure-Java Interop: A Better Java than Java"
Track:
Java, the Platform
Time: Wednesday 10:35 - 11:35
Location: Olympic Room
Abstract:
In this talk you will learn how Clojure achieves these objectives, and how to use Clojure effectively in a mixed-language environment. You will see:
Clojure's approach to Java interop achieves three goals: It
- is easier to use than Java itself
- provides access to the best possible JVM performance when you need
- encourages a style of programming that uses the good parts of Java
In this talk you will learn how Clojure achieves these objectives, and how to use Clojure effectively in a mixed-language environment. You will see:
- calling Java from Clojure, and Clojure from Java
- using macros such as doto to eliminate boilerplate code
- why you want protocols, not interfaces
- keeping your data out of walled gardens: records vs. classes
- working with legacy code: genclass, proxy, and annotations
- using type hinting for "pay as you go" performance tuning
- how to deal with the primitive/Object divide
