public interface CharSortedSet
extends CharSet, java.util.SortedSet<java.lang.Character>, CharBidirectionalIterable

A type-specific SortedSet; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this interface strengthens iterator(), comparator() (for primitive types), SortedSet.subSet(Object,Object), SortedSet.headSet(Object) and SortedSet.tailSet(Object).

Method Detail

iterator

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 on the element in this set, starting at the given element.

Throws:

java.lang.UnsupportedOperationException - if this set does not support iterators with a starting point.

iterator

CharBidirectionalIterator iterator()

Returns a type-specific BidirectionalIterator on the elements in this set.

Note that this specification strengthens the one given in the corresponding type-specific Collection.

This method returns a parameterised bidirectional iterator. The iterator can be moreover safely cast to a type-specific iterator.

subSet

CharSortedSet subSet(char fromElement,
                     char toElement)

Note that this specification strengthens the one given in SortedSet.subSet(Object,Object).

See Also:

SortedSet.subSet(Object,Object)

headSet

CharSortedSet headSet(char toElement)
