public class FilterListIterator extends Object implements ListIterator
ListIterator using a predicate to filter elements.
This iterator decorates the underlying iterator, only allowing through
those elements that match the specified Predicate.

FilterListIterator(ListIterator iterator,
Predicate predicate)
Constructs a new
FilterListIterator. |
