Note that Plume Util defines other classes in the org.plumelib.util package.

Collections and iterators

Hasher

The Hasher interface is an optional argument to a hash table (such as WeakHasherMap) that specifies the hashCode() and equals() methods.

WeakHasherMap

WeakHashMap is a modified version of WeakHashMap, that adds a constructor that takes a Hasher argument.

WeakIdentityHashMap

WeakIdentityHashMap is a modified version of WeakHashMap, that uses System.identityHashCode() rather than the object's hash code.

Class	Description
Hasher	Hasher is intended to work like Comparable: it is an optional argument to a hashing data structure (such as some implementations of HashSet, HashMap, or WeakHashMap) which specifies the hashCode() and equals() methods.
WeakHasherMap<K,V>	This is a modified version of WeakHashMap from JDK 1.2.2, that adds a constructor that takes a Hasher argument.
WeakIdentityHashMap<K,V>	This class combines the features of WeakHashMap and IdentityHashMap.
