Class DeferredMap

  • All Implemented Interfaces:
    java.util.Map<java.lang.Object,​java.lang.Object>
    public class DeferredMap
extends java.util.AbstractMap<java.lang.Object,​java.lang.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.
