Class TObjectIdentityHashingStrategy<T>

java.lang.Object
  org.elasticsearch.util.gnu.trove.TObjectIdentityHashingStrategy<T>

All Implemented Interfaces:

java.io.Serializable, TObjectHashingStrategy<T>

public final class TObjectIdentityHashingStrategy<T>
extends java.lang.Object
implements TObjectHashingStrategy<T>

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.
