public class ArrayListValuedHashMap<K,V> extends AbstractListValuedMap<K,V> implements java.io.Serializable
ListValuedMap
, using a HashMap
to provide data
storage and ArrayList
s as value collections. This is the standard
implementation of a ListValuedMap.
Note that ArrayListValuedHashMap is not synchronized and is not thread-safe. If you wish to use this map from multiple threads concurrently, you must use appropriate synchronization. This class may throw exceptions when accessed by concurrent threads without synchronization.
