ringbuffer的特别之处

tech2024-10-23  15

ringbuffer到底是什么? 嗯,正如名字所说的一样,它是一个环(首尾相接的环),你可以把它用做在不同上下文(线程)间传递数据的buffer。

我们实现的ring buffer和大家常用的队列之间的区别是,我们不删除buffer中的数据,也就是说这些数据一直存放在buffer中,直到新的数据覆盖他们。这就是和维基百科版本相比,我们不需要尾指针的原因。ringbuffer本身并不控制是否需要重叠(决定是否重叠是生产者-消费者行为模式的一部分–如果你等不急我写blog来说明它们,那么可以自行检出Disruptor项目)。
