Hi, I'm trying to understand how the Spliterator.characteristics are maintained across stream operations and I'm a bit confused. Maybe someone here can clear it up for me
s.sorted().spliterator() -> Spliterator.SORTED = true But if I use specify a comparator the stream is not sorted s.sorted((a,b) -> 1).spliterator() -> Spliterator.SORTED = false s.distinct().spliterator() -> Spliterator.DISTINCT = true but limiting the number of distinct elements makes the stream non distinct s.distinct().limit(10).spliterator() -> Spliterator.DISTINCT = false On the other hand something like Spliterator.SORTED is maintained when I invoke limit s.sorted().limit(10).spliterator() -> Spliterator.SORTED = true A flag such as Spliterator.NONNULL is also cleared in situations where it should not be. In my opinion an operation such as filter(predicate) should not flip the flag. Finally, are there any relationship between Spliterator.SORTED and Spliterator.ORDERED. I would think that a stream cannot be sorted without it also being ordered? but s.sorted().unordered().spliterator returns ORDERED=false and SORTED=true Cheers Kasper
