SetValuedMap, using a HashMap to provide data
storage and HashSets as value collections. This is the standard
implementation of a SetValuedMap.
Note that HashSetValuedHashMap 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.

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