Class ObjectElementMap

java.lang.Object
  ora.util.ObjectElementMap

public class ObjectElementMap
extends java.lang.Object

Author:

Kristian Martin This class heals the fact that two not equal object can have the same hashcode provided by System.identityHashCode The earlier implementation used a IdentityHashMap. Because of lost of uniqueness for large numbers of objects this approach was choosen. Hope this keeps stable for some time.... The approach numberate objects with same identityhashcode.
