什么增量编码/ COM pression算法库，在那里的Java？ [英] What Delta Encoding/Compression Algorithm libraries are there for Java?

问题描述

所以我在增量编码和我四周寻找一些好的这样的例子。我的认为的谷歌浏览器使用类似的东西进行补丁更新，的rsync 可能，以及维基百科的文章暗示了很多在线备份工具使用。

So I'm reading up on delta encoding, and I was looking around for some good examples of it. I think Google Chrome uses something like that for patch updates, rsync might, and the Wikipedia article implies that alot of online backup tools use this.

我如果有任何好的Java库，在那里，做这样的工作感到好奇？似乎有* nix中和C为基础的工具，但很少或根本没有的Java等价物做的远远超过COM preSS数据结构的丰富。

I'm curious if there are any good Java libraries out there that do this kind of work? There seem to be an abundance of *nix and C-based tools, but little or no Java equivalents that do much more than compress data structures.

在任何情况下，这对我来说是一个全新的概念，所以我很好奇，对任何事情读了，在看到有人用Java做一个特别的兴趣。

In any event, this is an entirely new concept for me, so I'm curious to read up on anything about it, with a particular interest in seeing anyone using Java to do it.

推荐答案

维基百科列出了一些Java实现的VCDIFF三角洲格式。

也存在的 rsync的算法，它可以用来创建二进制diff文件的Java实现。他们似乎并不生产准备，但如果你只是想看看code他们很好。请参见任何rsync的好库的Java？。

There also exist Java implementations of the rsync algorithm, which can be used to create binary diffs. They don't seem production-ready, but if you just want to see the code they're fine. See Any good rsync library for Java?.
