Method Details
-
delegate
Description copied from class:ForwardingObjectReturns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such asForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.- Specified by:
delegatein classForwardingMap<K,V>
-
forcePut
Description copied from interface:BiMapAn alternate form ofputthat silently removes any existing entry with the valuevaluebefore proceeding with theBiMap.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:
forcePutin interfaceBiMap<K,V> - Parameters:
key- the key with which the specified value is to be associatedvalue- the value to be associated with the specified key- Returns:
- the value that was previously associated with the key, or
nullif there was no previous entry. (If the bimap contains null values, thenforcePut, likeput, returnsnullboth if the key is absent and if it is present with a null value.)

inverse
Description copied from interface:BiMapReturns 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.
-
values
Description copied from interface:BiMapBecause a bimap has unique values, this method returns a
Set, instead of theCollectionspecified in theMapinterface.
