Implementation of Vector Clocks
提问by
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.
对于在不同设备上运行的代码，我需要确定在这些设备之间发送的消息的顺序。因此，我想使用矢量时钟，因为我读过矢量时钟允许对事件进行排序。
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?
我可以使用任何已建立的框架/公共 API 吗？或者参考实现=或者我必须从头开始编码吗？
Thanks for any references and hints
感谢您的任何参考和提示

A VectorClockimplementation is available from Google Code.
Google CodeVectorClock提供了一个实现。
You could also look at the patches to add vector clock support in Cassandra.
您还可以查看补丁以在Cassandra 中添加矢量时钟支持。
You should also read the wiki [1][2]for limitations of the technique and other alternatives.

I found this vector clock written in Java as a part of project voldemort.
我发现这个矢量时钟是用 Java 编写的，是项目 voldemort的一部分。
Here's a link to the source code. You'll need to also pull down the class and interface references.
这是源代码的链接。您还需要下拉类和接口引用。
