Class Map

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap

hlt.language.util.Map

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map

public class Map
extends java.util.HashMap

Extends HashMap with equals and hashCode methods to allow "higher-order" maps (i.e., Maps of Maps).

NB: Of course, testing and storing a Map works only if it is immutable (nothing more is put into or removed from it after being initially filled). This is enforced by setting a lock as soon as either equals or hashCode is used on a given Map.
