Method Detail

inverse

public ImmutableBiMap<java.lang.Object,java.lang.Object> 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<java.lang.Object,java.lang.Object>

Specified by:

inverse in class ImmutableBiMap<java.lang.Object,java.lang.Object>

Returns:

the inverse view of this bimap

size

public int size()

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface java.util.Map<java.lang.Object,java.lang.Object>

Overrides:

isEmpty in class ImmutableMap<java.lang.Object,java.lang.Object>

get

public java.lang.Object get(@Nullable
                            java.lang.Object key)

Specified by:

get in interface java.util.Map<java.lang.Object,java.lang.Object>

Specified by:

get in class ImmutableMap<java.lang.Object,java.lang.Object>

entrySet

public ImmutableSet<java.util.Map.Entry<java.lang.Object,java.lang.Object>> entrySet()

Description copied from class: ImmutableMap

Returns an immutable set of the mappings in this map. The entries are in the same order as the parameters used to build this map.

Specified by:

entrySet in interface java.util.Map<java.lang.Object,java.lang.Object>

Overrides:

entrySet in class ImmutableMap<java.lang.Object,java.lang.Object>

createEntrySet

ImmutableSet<java.util.Map.Entry<java.lang.Object,java.lang.Object>> createEntrySet()

Specified by:

createEntrySet in class ImmutableMap<java.lang.Object,java.lang.Object>

asMultimap

public ImmutableSetMultimap<java.lang.Object,java.lang.Object> asMultimap()

Description copied from class: ImmutableMap

Returns a multimap view of the map.

Overrides:

asMultimap in class ImmutableMap<java.lang.Object,java.lang.Object>

keySet

public ImmutableSet<java.lang.Object> keySet()

Description copied from class: ImmutableMap

Returns an immutable set of the keys in this map. These keys are in the same order as the parameters used to build this map.

Specified by:

keySet in interface java.util.Map<java.lang.Object,java.lang.Object>

Overrides:

keySet in class ImmutableMap<java.lang.Object,java.lang.Object>

isPartialView

boolean isPartialView()

Specified by:

isPartialView in class ImmutableMap<java.lang.Object,java.lang.Object>

readResolve

java.lang.Object readResolve()
