public interface LongSortedSet extends LongSet, java.util.SortedSet<java.lang.Long>
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)
.

LongBidirectionalIterator iterator(long fromElement)
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.
fromElement
- an element to start from.java.lang.UnsupportedOperationException
- if this set does not support iterators with a starting point.@Deprecated LongBidirectionalIterator longIterator()

5, replaced by iterator()
.BidirectionalIterator
iterator on the collection.
The iterator returned by the iterator()
method and by this
method are identical; however, using this method you can save a type casting.
Note that this specification strengthens the one given in the corresponding type-specific
Collection
.
longIterator

LongCollection.iterator()
LongBidirectionalIterator iterator()
BidirectionalIterator
on the elements in
this set.
This method returns a parameterised bidirectional iterator. The iterator
can be moreover safely cast to a type-specific iterator.
Note that this specification strengthens the one given in the corresponding type-specific
Collection
.
