ForwardingNavigableMap.StandardDescendingMap (Guava: Google Core Libraries for Java 19.0 API)

java.lang.Object
- com.google.common.collect.ForwardingObject
- - com.google.common.collect.ForwardingMap<K,V>
  - - com.google.common.collect.ForwardingNavigableMap.StandardDescendingMap

All Implemented Interfaces:

Map<K,V>, NavigableMap<K,V>, SortedMap<K,V>

Enclosing class:

ForwardingNavigableMap<K,V>
```
@Beta
protected class ForwardingNavigableMap.StandardDescendingMap
extends ForwardingMap<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.

Since:

12.0

protected final Map<K,V> 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 as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.
