How do streams stop?

Question

I was wondering when I created my own infinite stream with Stream.generate how the Streams which are in the standard library stop...

For example when yo

Answer 1

I have created a generic workaround for this

public class GuardedSpliterator implements Spliterator {

  final Supplier generator;

  final Predicate termination;

  final boolean inclusive;

  public GuardedSpliterator(Supplier generator, Predicate termination, boolean inclusive) {
    this.generator = generator;
    this.termination = termination;
    this.inclusive = inclusive;
  }

  @Override
  public boolean tryAdvance(Consumer action) {
    T next = generator.get(); 
    boolean end = termination.test(next);
    if (inclusive || !end) {
      action.accept(next);
    }
    return !end;
  }

  @Override
  public Spliterator trySplit() {
    throw new UnsupportedOperationException("Not supported yet.");
  }

  @Override
  public long estimateSize() {
    throw new UnsupportedOperationException("Not supported yet.");
  }

  @Override
  public int characteristics() {
    return Spliterator.ORDERED;
  }

}

Usage is pretty easy:

GuardedSpliterator source = new GuardedSpliterator<>(
    ()  -> rnd.nextInt(),
    (i) -> i > 10,
    true
);

Stream ints = StreamSupport.stream(source, false);

ints.forEach(i -> System.out.println(i));
