Example 4 with IntConsumer

use of java8.util.function.IntConsumer in project streamsupport by stefan-zobel.

the class Spliterators method iterator.

/**

 * <p>Traversal of elements should be accomplished through the iterator.
 * The behaviour of traversal is undefined if the spliterator is operated
 * after the iterator is returned.

 * @param spliterator The spliterator
 * @return An iterator
 * @throws NullPointerException if the given spliterator is {@code null}
