T
- The element type of the iterator and the collectionIterable<T>
, Collection<T>
public class IteratorCollection<T> extends AbstractCollection<T>
Collection
that lazily reads its elements from an
Iterator
.
In other words, you can call iterator()
as often as you want, but the
IteratorCollection
will iterate over its delegate only once.
