DETAIL: FIELD | CONSTR | METHOD

org.apache.cxf.common.util
Class WeakIdentityHashMap<K,V>

java.lang.Object
  org.apache.cxf.common.util.WeakIdentityHashMap<K,V>

All Implemented Interfaces:: Map<K,V>

public class WeakIdentityHashMap<K,V>
extends Object
implements Map<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.
