org.zkoss.util.IdentityHashSet
- All Implemented Interfaces:
- java.io.Serializable, java.lang.Cloneable, java.lang.Iterable, java.util.Collection, java.util.Set
public class IdentityHashSet
- extends java.util.AbstractSet
- implements java.util.Set, java.lang.Cloneable, java.io.Serializable
Like java.util.InternalHashMap, it uses == and System.identityHashCode
for doing HashSet.
