get counter value的意思|示意

Note that all the methods, even get(), need to be synchronized for the class to be thread-safe, to ensure that no updates are lost, and that all threads see the most recent value of the counter.

注意所有方法，甚至需要同步 get()，使类成为线程安全的类，从而确保没有任何更新信息丢失，所有线程都看到计数器的最新值。

You then use register 127 as your loop counter and register 126 as your base pointer, and perform convert_to_upper on each value until you get to the end of the buffer.

然后再将寄存器127用作循环计数器，将寄存器126用作基指针，并在每个值上执行convert _ to_upper，直到到达缓冲区的底部为止。
