All Implemented Interfaces:

Iterable<E>, Collection<E>, NavigableSet<E>, SequencedCollection<E>, SequencedSet<E>, Set<E>, SortedSet<E>

Enclosing class:

ForwardingNavigableSet<E extends @Nullable Object>

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.

Method Details

delegate

protected 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.

Specified by:

delegate in class ForwardingNavigableSet<E extends @Nullable Object>

lower
