Package com.fasterxml.jackson.jr.ob.impl

Class DeferredMap

java.lang.Object

java.util.AbstractMap<Object,Object>

com.fasterxml.jackson.jr.ob.impl.DeferredMap

All Implemented Interfaces:

Map<Object,Object>

public class DeferredMap
extends AbstractMap<Object,Object>

A specialized Map implementation that will collect entries during building, but only materialize full lookup structure when needed; that is, actual building of hash lookup is deferred.

Inspired by lazily initialized Map used by Boon library.
