Class TObjectIdentityHashingStrategy

java.lang.Object
  |
  +--gnu.trove.TObjectIdentityHashingStrategy
All Implemented Interfaces:
java.io.Serializable, TObjectHashingStrategy

public final class TObjectIdentityHashingStrategy
extends java.lang.Object
implements TObjectHashingStrategy

This object hashing strategy uses the System.identityHashCode method to provide identity hash codes. These are identical to the value produced by Object.hashCode(), even when the type of the object being hashed overrides that method. Created: Sat Aug 17 11:13:15 2002
