public static class CharSortedSets.EmptySet extends CharSets.EmptySet implements CharSortedSet, java.io.Serializable, java.lang.Cloneable
This class may be useful to implement your own in case you subclass a type-specific sorted set.

Note that the corresponding method of the type-specific collection is rem()
.
This unfortunate situation is caused by the clash
with the similarly named index-based method in the List
interface.

CharSortedSet
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.
