Enclosing class:

Definition

public static final class Definition.MethodKey
extends java.lang.Object

Key for looking up a method.

Methods are keyed on both name and arity, and can be overloaded once per arity. This allows signatures such as String.indexOf(String) vs String.indexOf(String, int).

It is less flexible than full signature overloading where types can differ too, but better than just the name, and overloading types adds complexity to users, too.
