Method Detail

delegate

BiMap<K,V> delegate()

Overrides:

delegate in class Synchronized.SynchronizedMap<K,V>

values

public java.util.Set<V> values()

Description copied from interface: BiMap

Because a bimap has unique values, this method returns a Set, instead of the Collection specified in the Map interface.

Specified by:

values in interface BiMap<K,V>

Specified by:

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

Overrides:

values in class Synchronized.SynchronizedMap<K,V>

forcePut

public V forcePut(K key,
                  V value)

Description copied from interface: BiMap

An alternate form of put that silently removes any existing entry with the value value before proceeding with the BiMap.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.

Specified by:

forcePut in interface BiMap<K,V>

Parameters:

key - the key with which the specified value is to be associated

value - the value to be associated with the specified key

Returns:

the value which was previously associated with the key, which may be null, or null if there was no previous entry

inverse

public BiMap<V,K> inverse()

Description copied from interface: BiMap

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.

Specified by:

inverse in interface BiMap<K,V>

Returns:

the inverse view of this bimap
