iterator
public CharBidirectionalIterator iterator(char from)
Description copied from interface:CharSortedSet
Returns a type-specificBidirectionalIterator
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 returnfalse
). 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 returnfalse
).Note that passing the last element of the set as starting point and calling
previous()
you can traverse the entire set in reverse order.- Specified by:
iterator
in interfaceCharSortedSet
- Parameters:
from
- an element to start from.- Returns:
- a bidirectional iterator on the element in this set, starting at the given element.
