org.apache.commons.collections.SortedBidiMap |
Known Indirect Subclasses |
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.

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()
.

The inverse map returned by inverseBidiMap()
should be the
same object as returned by this method.
