java.lang.Objectit.unimi.dsi.fastutil.longs.AbstractLongCollection
it.unimi.dsi.fastutil.longs.AbstractLongSet
it.unimi.dsi.fastutil.longs.AbstractLongSortedSet
it.unimi.dsi.fastutil.longs.LongRBTreeSet
A type-specific red-black tree set with a fast, small-footprint implementation.
The iterators provided by this class are type-specific bidirectional iterators
.
Moreover, the iterator returned by iterator()
can be safely cast
to a type-specific list iterator.

The iterator returned by the Collection.iterator()
method and by this
method are identical; however, using this method you can save a type casting.

public LongBidirectionalIterator iterator(long from)
LongSortedSet
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.

This method performs a deep copy of this tree set; the data stored in the set, however, is not cloned. Note that this makes a difference only for object keys.
