code: public static <T> Collection<T> reject(
              Iterable<T> iterable,
              Predicate<? super T> predicate,
              boolean allowReorderedResult)
      {
          return ParallelIterate.reject(iterable, predicate, null, allowReorderedResult);
      }
docs: Same effect as {@link Iterate#reject(Iterable, Predicate)}, but executed in parallel batches,
  and with a potentially reordered result.
  
  @param allowReorderedResult If the result can be in a different order.
  Allowing reordering may yield faster execution.
  @return The rejected elements. The Collection will be of the same type (List or Set) as the input.
