public interface LongSortedSet
extends LongSet, SortedSet<Long>, LongBidirectionalIterable

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

LongBidirectionalIterator iterator(long 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:

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

iterator

LongBidirectionalIterator 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.

Specified by:

iterator in interface Collection<Long>

Specified by:

iterator in interface Iterable<Long>

Specified by:

iterator in interface LongBidirectionalIterable

Specified by:

iterator in interface LongCollection

Specified by:

Specified by:

iterator in interface LongSet

Specified by:

iterator in interface Set<Long>

Returns:

a bidirectional iterator on the element in this set.

Iterable.iterator()

subSet

LongSortedSet subSet(long fromElement,
                     long toElement)

Returns a view of the portion of this sorted set whose elements range from fromElement, inclusive, to toElement, exclusive.

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

See Also:

SortedSet.subSet(Object,Object)

headSet

LongSortedSet headSet(long toElement)

Returns a view of the portion of this sorted set whose elements are strictly less than toElement.

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

See Also:

SortedSet.headSet(Object)

tailSet

LongSortedSet tailSet(long fromElement)

Returns a view of the portion of this sorted set whose elements are greater than or equal to fromElement.

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

See Also:

SortedSet.tailSet(Object)

comparator

LongComparator comparator()

Note that this specification strengthens the one given in SortedSet.comparator().

Specified by:

comparator in interface SortedSet<Long>

firstLong

long firstLong()

Returns the first (lowest) element currently in this set.

See Also:

SortedSet.first()
