public abstract class AbstractObjectBidirectionalIterator<K> extends AbstractObjectIterator<K> implements ObjectBidirectionalIterator<K>
To create a type-specific bidirectional iterator, besides what is needed for an iterator you need both a method returning the previous element as primitive type and a method returning the previous element as an object. However, if you inherit from this class you need just one (anyone).
This class implements also a trivial version of back(int)
that
uses type-specific methods.

This method just iterates the type-specific version of
BidirectionalIterator.previous() for
at most n times, stopping if BidirectionalIterator.hasPrevious() becomes false. |
