public interface BidirectionalIterator<K>
extends Iterator<K>

A bidirectional Iterator.

This kind of iterator is essentially a ListIterator that does not support ListIterator.previousIndex() and ListIterator.nextIndex(). It is useful for those maps that can easily provide bidirectional iteration, but provide no index.

Note that iterators returned by fastutil classes are more specific, and support skipping. This class serves the purpose of organising in a cleaner way the relationships between various iterators.
