delegate()
Returns the backing delegate instance that methods are forwarded to.

V |
forcePut(K key,
V value)
An alternate form of
put that silently removes any existing entry with the value value before proceeding with the BiMap.put(K, V) operation. |
BiMap<V,K> |
inverse()
Returns the inverse view of this bimap, which maps each of this bimap's values to its
associated key.

public V forcePut(K key, V value)
BiMap
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.
