- All Implemented Interfaces:
Map<K,

,V> SequencedMap<K,
,V> SortedMap<K,
V>
- Enclosing class:
ForwardingNavigableMap<K,
V>
A sensible implementation of
NavigableMap.descendingMap()
in terms of the methods of
this NavigableMap
. In many cases, you may wish to override
ForwardingNavigableMap.descendingMap()
to forward to this implementation or a subclass
thereof.
In particular, this map iterates over entries with repeated calls to
NavigableMap.lowerEntry(K)
. If a more efficient means of iteration is available, you may
wish to override the entryIterator()
method of this class.

delegate
Description copied from class:ForwardingObject
Returns 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:
