Class HashMultiMap<Key,Value>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<Key,Collection<Value>>

fr.vergne.collection.impl.AbstractMultiMap<Key,Value>

fr.vergne.collection.impl.HashMultiMap<Key,Value>

Type Parameters:

Key -

Value -

All Implemented Interfaces:

MultiMap<Key,Value>, Serializable, Cloneable, Iterable<Map.Entry<Key,Value>>, Map<Key,Collection<Value>>

public class HashMultiMap<Key,Value>
extends AbstractMultiMap<Key,Value>
implements MultiMap<Key,Value>

A HashMultiMap is a MultiMap which allows at most one instance for each (key, value). If the same value is assigned several times to the same key, it is the same than providing it only once, and removing it once is enough to not have it anymore in the map.
