Interface SortedBidiMap<K,V>
- Type Parameters:
K
- the type of the keys in the mapV
- the type of the values in the map
- All Superinterfaces:
- BidiMap<K,V>, Get<K,V>, IterableGet<K,V>, IterableMap<K,V>, Map<K,V>, OrderedBidiMap<K,V>, OrderedMap<K,V>, Put<K,V>, SortedMap<K,V>
- All Known Implementing Classes:
- AbstractSortedBidiMapDecorator, DualTreeBidiMap, UnmodifiableSortedBidiMap
public interface SortedBidiMap<K,V>
- extends OrderedBidiMap<K,V>, SortedMap<K,V>
Defines a map that allows bidirectional lookup between key and values
and retains both keys and values in sorted order.
Implementations should allow a value to be looked up from a key and
a key to be looked up from a value with equal performance.

inverseBidiMap
SortedBidiMap<V,K> inverseBidiMap()
- Gets a view of this map where the keys and values are reversed.
Changes to one map will be visible in the other and vice versa.
This enables both directions of the map to be accessed equally.
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.
Implementations must return a SortedBidiMap
instance,
usually by forwarding to inverseSortedBidiMap()
.
- Specified by:
inverseBidiMap
in interface BidiMap<K,V>
- Specified by:
inverseBidiMap
in interface OrderedBidiMap<K,V>
- Returns:
- an inverted bidirectional map
valueComparator
Comparator<? super V> valueComparator()
- Get the comparator used for the values in the value-to-key map aspect.
- Returns:
- Comparator super V>
