Class IdentityMap

  • All Implemented Interfaces:
    java.util.Map
    public final class IdentityMap
extends java.lang.Object
implements java.util.Map
    An IdentityMap that uses reference-equality instead of object-equality. According to its special function it violates some design contracts of the Map interface.
