      danger.util.IdentityHashtable

All Implemented Interfaces:

Serializable, Cloneable, Map

public class IdentityHashtable
extends Dictionary
implements Map, Cloneable, Serializable

An implementation of the J2SE IdentityHashMap class, using the Hashtable interface for CLDC consistency. Keys are hashed using System.identityHashCode(key), instead of key.hashCode(), and reference equality is used instead of key.equals(key2).

This class is thread-safe.
