Dispatch takes many forms. Single dispatch, switch statements, pattern matching, and multiple dispatch all meet similar needs: Selecting runtime behavior in response to varying runtime conditions.

Flexible dispatch is a key element of Java.next. All of the Java.next languages support dispatch strategies that are far more flexible than Java's single dispatch.

In this talk (Part 3 of the Java.next series), I will explore how the Java.next languages (Clojure, Groovy, JRuby, and Scala) support dispatch. For more information, see the Java.next Dispatch article on the Relevance blog.
