Class IdentitySet

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