trySplit

Spliterator.OfLong trySplit ()

如果这个分割器可以被分割，返回一个Spliterator覆盖元素，当从这个方法返回时，不会被这个分割器覆盖。

如果此Spliterator为 ORDERED ，则返回的Spliterator必须覆盖元素的严格前缀。

除非此Spliterator覆盖无限数量的元素，否则重复调用trySplit()必须最终返回null 。 非空返回时：

• the value reported for estimateSize() before splitting, must, after splitting, be greater than or equal to estimateSize() for this and the returned Spliterator; and
• if this Spliterator is SUBSIZED, then estimateSize() for this spliterator before splitting must be equal to the sum of estimateSize() for this and the returned Spliterator after splitting.

此方法可能因任何原因返回 null ，包括空行，遍历开始后无法拆分，数据结构约束和效率考虑。
