Class LazyMap

java.lang.Object

java.util.AbstractMap<String,Object>

groovy.json.internal.LazyMap

All Implemented Interfaces:

Map<String,Object>

public class LazyMap
extends AbstractMap<String,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.
