      @Beta
      protected class ForwardingNavigableSet.StandardDescendingSet
      extends ForwardingNavigableSet<E>

  A sensible implementation of `NavigableSet.descendingSet()` in terms of the other methods of `NavigableSet`, notably including `NavigableSet.descendingIterator()`.

  In many cases, you may wish to override `ForwardingNavigableSet.descendingSet()` to forward to this implementation or a subclass thereof.

      Constructor for use by subclasses.

  - ### Method Detail

    - #### delegate

          protected java.util.NavigableSet<E> 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.
