BidiMapSet view of the values contained in this map.
The set is backed by the map, so changes to the map are reflected
in the set, and vice-versa. If the map is modified while an iteration
over the set is in progress (except through the iterator's own
remove operation), the results of the iteration are undefined.
The set supports element removal, which removes the corresponding
mapping from the map, via the Iterator.remove,
Collection.remove, removeAll,
retainAll and clear operations. It does not
support the add or addAll operations.values in interface Map<K,V>values in interface SortedMap<K,V>values in interface BidiMap<K,V>values in interface Get<K,V>values in class AbstractBidiMapDecorator<K,V>Map.values()public K removeValue(Object value)
BidiMap
If the value is not contained in the map, null is returned.
Implementations should seek to make this method perform equally as well
as remove(Object).

AbstractIterableMapMapIterator over the map.
A map iterator is an efficient way of iterating over maps. There is no need to access the entry set or use Map Entry objects.
IterableMap<String,Integer> map = new HashedMap<String,Integer>();
MapIterator<String,Integer> it = map.mapIterator();
while (it.hasNext()) {
String key = it.next();
Integer value = it.getValue();
it.setValue(value + 1);
}

BidiMap
Changes to one map will be visible in the other and vice versa.
This enables both directions of the map to be accessed as a Map.
Implementations should seek to avoid creating a new object every time this
method is called. See AbstractMap.values() etc. Calling this
method on the inverse map should return the original.
