比较两long个数组在指定的范围上,以数字方式将元素视为无符号。 如果两个数组在指定范围中共享一个公共前缀,则字典比较是比较两个元素的结果,就好像在Long#compareUnsigned(long, long)作为前缀长度的相应数组内的相对索引处进行比较。 否则,一个数组是另一个数组的正确前缀,字典比较是比较两个范围长度的结果。 (请...

incrementAndGet()、decrementAndGet() 或 addAndGet(int delta) 或 addAndGet(long delta):先进行增加、减少或者加上指定的增量,然后再获取当前值。 compareAndSet(int expect, int update) 或 compareAndSet(long expect, long update):如果当前值等于期望值,则以原子方式将该值设置为给定的更新值。
