Class IdentityHashSet<T>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractSet<T>

org.proxy4j.core.struct.IdentityHashSet<T>

All Implemented Interfaces:

Iterable<T>, Collection<T>, Set<T>

public class IdentityHashSet<T>
extends AbstractSet<T>
implements Set<T>

A Set implementation based on reference (not object) equality. This is an intentional violation of the Set.equals(Object) contract for specialized purposes. Uses a backing instance of IdentityHashMap.
