comparator
public LongComparator comparator()
- Description copied from interface:
LongSortedSet
- Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering.
Note that this specification strengthens the one given in SortedSet.comparator()
.
- See Also:
SortedSet.comparator()
firstLong
public long firstLong()
- See Also:
SortedSet.first()
lastLong
public long lastLong()
- See Also:
SortedSet.last()
headSet
public LongSortedSet headSet(long to)
- See Also:
SortedSet.headSet(Object)
tailSet
public LongSortedSet tailSet(long from)
- See Also:
SortedSet.tailSet(Object)
subSet
public LongSortedSet subSet(long from,
long to)
- See Also:
SortedSet.subSet(Object,Object)
iterator
public LongBidirectionalIterator iterator(long from)
- Description copied from interface:
LongSortedSet
- 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:
from
- an element to start from.
- Returns:
- a bidirectional iterator on the element in this set, starting at the given element.
iterator
public LongBidirectionalIterator iterator()
- Description copied from interface:
LongCollection
- Returns a type-specific iterator on the elements of this collection.
Note that this specification strengthens the one given in
Iterable.iterator()
, which was already
strengthened in the corresponding type-specific class,
but was weakened by the fact that this interface extends Collection
.
