Class LazyMap

java.lang.Object

java.util.AbstractMap<java.lang.String,java.lang.Object>

org.boon.collections.LazyMap

All Implemented Interfaces:

java.util.Map<java.lang.String,java.lang.Object>

public class LazyMap
extends java.util.AbstractMap<java.lang.String,java.lang.Object>

This maps only builds once you ask for a key for the first time. It is designed to not incur the overhead of creating a map unless needed.
