inverse

public ImmutableBiMap<V,K> inverse()

Description copied from class: ImmutableBiMap

Returns the inverse view of this bimap, which maps each of this bimap's values to its associated key. The two bimaps are backed by the same data; any changes to one will appear in the other.

Note:There is no guaranteed correspondence between the iteration order of a bimap and that of its inverse.

The inverse of an ImmutableBiMap is another ImmutableBiMap.

Specified by:

inverse in interface BiMap<K,V>

Specified by:

inverse in class ImmutableBiMap<K,V>

Returns:

the inverse view of this bimap

get

public V get(java.lang.Object key)

Specified by:

get in interface java.util.Map<K,V>

Specified by:

get in class ImmutableMap<K,V>

createEntrySet

ImmutableSet<java.util.Map.Entry<K,V>> createEntrySet()

Specified by:

createEntrySet in class ImmutableMap<K,V>

createKeySet

ImmutableSet<K> createKeySet()

Specified by:

createKeySet in class ImmutableMap<K,V>

isPartialView

boolean isPartialView()

Specified by:

isPartialView in class ImmutableMap<K,V>
