Interface OrderedBidiMap<K,V> 
- Type Parameters:
- K- the type of the keys in the map
- V- 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> - OrderedMap<K,,- V> - Put<K,- V> 
- All Known Subinterfaces:
- SortedBidiMap<K,- V> 
- All Known Implementing Classes:
- AbstractOrderedBidiMapDecorator,- AbstractSortedBidiMapDecorator,- DualTreeBidiMap,- TreeBidiMap,- UnmodifiableOrderedBidiMap,- UnmodifiableSortedBidiMap
Defines a map that allows bidirectional lookup between key and values
 and retains and provides access to an ordering.
 
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.

Method Details- 
inverseBidiMapGets 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 an OrderedBidiMapinstance, usually by forwarding toinverseOrderedBidiMap().- Specified by:
- inverseBidiMapin interface- BidiMap<K,- V> 
- Returns:
- an inverted bidirectional map
