|Modifier and Type||Method and Description|
An alternate form of
Returns the inverse view of this bimap, which maps each of this bimap's values to its associated key.
Associates the specified value with the specified key in this map (optional operation).
Copies all of the mappings from the specified map to this map (optional operation).
@CanIgnoreReturnValue V put(K key, V value)
m.containsKey(k)would return true.)
key- key with which the specified value is to be associated
value- value to be associated with the specified key
IllegalArgumentException- if the given value is already bound to a different key in this bimap. The bimap will remain unmodified in this event. To avoid this exception, call
@CanIgnoreReturnValue V forcePut(K key, V value)
putthat silently removes any existing entry with the value
valuebefore proceeding with the
put(K, V)operation. If the bimap previously contained the provided key-value mapping, this method has no effect.
Note that a successful call to this method could cause the size of the bimap to increase by one, stay the same, or even decrease by one.
Warning: If an existing entry with this value is removed, the key for that entry is discarded and not returned.
key- the key with which the specified value is to be associated
value- the value to be associated with the specified key
nullif there was no previous entry
put(k, v)on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress.
Warning: the results of calling this method may vary depending on the iteration order
Collectionview of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
Note:There is no guaranteed correspondence between the iteration order of a bimap and that of its inverse.
