public abstract class AbstractObjectBidirectionalIterator<K>
extends AbstractObjectIterator<K>
implements ObjectBidirectionalIterator<K>

An abstract class facilitating the creation of type-specific bidirectional iterators.

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.

Method Detail

back

public int back(int n)

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

Specified by:

back in interface ObjectBidirectionalIterator<K>

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.
