- Enclosing class:
- ForwardingNavigableMap<K extends @Nullable java.lang.Object,V extends @Nullable java.lang.Object>
protected class ForwardingNavigableMap.StandardDescendingMap extends ForwardingMap<K,V>
A sensible implementation ofNavigableMap.descendingMap()
in terms of the methods of thisNavigableMap
. In many cases, you may wish to overrideForwardingNavigableMap.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 theentryIterator()
method of this class.- Since:

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:
