public class ArrayListValuedHashMap<K,V> extends AbstractListValuedMap<K,V> implements Serializable
ListValuedMap, using a HashMap to provide data
storage and ArrayLists 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.
| Constructor and Description |

ArrayListValuedHashMap()
Creates an empty ArrayListValuedHashMap with the default initial
map capacity (16) and the default initial list capacity (3).
|
ArrayListValuedHashMap(int initialListCapacity)
Creates an empty ArrayListValuedHashMap with the default initial
map capacity (16) and the specified initial list capacity.
|
ArrayListValuedHashMap(int initialMapCapacity,
int initialListCapacity)
Creates an empty ArrayListValuedHashMap with the specified initial
map and list capacities.
|
ArrayListValuedHashMap(Map<? extends K,? extends V> map)
Creates an ArrayListValuedHashMap copying all the mappings of the given map.
|
ArrayListValuedHashMap(MultiValuedMap<? extends K,? extends V> map)
Creates an ArrayListValuedHashMap copying all the mappings of the given map.
