- All Implemented Interfaces:
- Map<K,V>
public class WeakIdentityHashMap<K,V>
extends Object
implements Map<K,V>
Implements a combination of WeakHashMap and IdentityHashMap.
 Useful for caches that need to key off of a == comparison
 instead of a .equals.
 
 This class is not a general-purpose Map implementation! While
 this class implements the Map interface, it intentionally violates
 Map's general contract, which mandates the use of the equals method
 when comparing objects. This class is designed for use only in the
 rare cases wherein reference-equality semantics are required.
 Note that this implementation is not synchronized.
