矢量时钟的实现
对于在不同设备上运行的代码，我需要确定这些设备之间发送的消息的顺序。因此，我想使用矢量时钟，因为我读到矢量时钟允许事件排序。
是否有我可以使用的已建立的框架/公共 API？或者参考实现= 或者我必须从头开始编码吗？
感谢您的任何参考和提示
For my code which is running on different devices, i need to determine the ordering of messages which are sent between those devices. Therefore I would like to use vector clocks since I read vector clocks allow for the ordering of events.
Is there any established framework/public API which I can use for that? Or a reference implementation= Or do I have to code it from scratch?
Thanks for any references and hints

VectorClock实现可从 Google 代码。您还可以查看 Cassandra 中添加矢量时钟支持的补丁。
您还应该阅读 wiki [1] [2] 了解该技术和其他替代方案的限制。

VectorClockimplementation is available from Google Code.You could also look at the patches to add vector clock support in Cassandra.
You should also read the wiki [1] [2] for limitations of the technique and other alternatives.
我发现这个矢量时钟是用 Java 编写的，作为 project voldemort 的一部分。
这是源代码。您还需要下拉类和接口引用。
以下是 Javadoc 的链接。
这是关于矢量时钟的维基百科文章。
I found this vector clock written in Java as a part of project voldemort.
Here's a link to the source code. You'll need to also pull down the class and interface references.

Here's a Wikipedia article on vector clocks.
