      common.HashMultiMapDiff
          common.IndexedMultiMapDiff

All Implemented Interfaces:

IndexedMultiMap, MultiMap, MultiMapDiff, java.lang.Cloneable, java.util.Map

public class IndexedMultiMapDiff
extends HashMultiMapDiff
implements IndexedMultiMap

A MultiMapDiff implementation that also implements the IndexedMultiMap interface. It is just like HashMultiMapDiff, except that it uses IndexedHashSetDiff objects rather than ordinary HashSetDiff objects.

IndexedMultiMapDiff

public IndexedMultiMapDiff(IndexedMultiMap underlying)

Creates a new IndexedMultiMapDiff with the given underlying 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.
