Constructor Detail

IndexedHashMultiMap

public IndexedHashMultiMap()

Creates a new, empty IndexedMultiMap.

IndexedHashMultiMap

public IndexedHashMultiMap(IndexedMultiMap orig)

Creates a new IndexedMultiMap that is initially equal to the given IndexedMultiMap.

Method Detail

get

public java.lang.Object get(java.lang.Object key)

Description copied from interface: MultiMap

Returns the set associated with the given key. If the key is not in the map, returns an empty set. The set returned is modifiable and backed by this multi-map: if values are added for the given key, they will show up in the returned set. However, the returned set may lose its connection to this multi-map if the multi-map's put method is called or if all the values for the given key are removed.
