Vector.isSequentialAccess介绍

[英]true if this implementation should be considered to be iterable in index order in an efficient way. In particular this implies that #all() and #nonZeroes() ()} return elements in ascending order by index.
[中]如果此实现应被视为可以以有效的方式按索引顺序执行，则为true。这尤其意味着#all（）和#nonzeres（）（）}按索引升序返回元素。
