public class FilterListIterator<E>
Decorates another ListIterator using a predicate to filter elements.
This iterator decorates the underlying iterator, only allowing through
those elements that match the specified Predicate.
| Constructor Summary | |
|---|---|
FilterListIterator()
Constructs a new FilterListIterator that will not function
until setListIterator
and setPredicate are invoked. |
|
FilterListIterator(ListIterator<? extends E> iterator)
Constructs a new FilterListIterator that will not
function until setPredicate is invoked. |
|
FilterListIterator(ListIterator<? extends E> iterator,
Predicate<? super E> predicate)
Constructs a new FilterListIterator. |
|
FilterListIterator(Predicate<? super E> predicate)
Constructs a new FilterListIterator that will not function
until setListIterator is invoked. |
