Interface CharSortedSet
- All Superinterfaces:
- CharCollection, CharSet, Collection, Set, SortedSet
- All Known Implementing Classes:
- AbstractCharSortedSet, CharAVLTreeSet, CharLinkedOpenHashSet, CharRBTreeSet, CharSortedSets.Singleton, CharSortedSets.SynchronizedSortedSet, Sets.EmptySet
- public interface CharSortedSet
- extends CharSet, SortedSet
A type-specific SortedSet
; provides some additional methods that use polymorphism to reduce type juggling.

iterator
public CharBidirectionalIterator iterator(char fromElement)
- Returns a type-specific
BidirectionalIterator
on the elements in
this set, starting from a given element of the domain (optional operation).
This method returns a type-specific bidirectional iterator with given
starting point. The starting point is any element comparable to the
elements of this set (even if it does not actually belong to the
set). The next element of the returned iterator is the least element of
the set that is greater than the starting point (if there are no
elements greater than the starting point, hasNext()
will return
false
). The previous element of the returned iterator is
the greatest element of the set that is smaller than or equal to the
starting point (if there are no elements smaller than or equal to the
starting point, hasPrevious()
will return false
).
Note that passing the last element of the set as starting point and
calling previous()
you can traverse the
entire set in reverse order.
- Parameters:
fromElement
- an element to start from.
- Returns:
- a bidirectional iterator iterator starting at the given element.
- Throws:
UnsupportedOperationException
- if this set does not support iterators with a starting point.
