what is revision in versionedHook?

[rafaelleru]

I'm working on webDAV support #38 and I was looking Dropbox repo, but I can not understand what is revision in:

VersionedRook book = new VersionedRook(
                                        repoUri,
                                        uri,
                                        file.getRev(),
                                        file.getServerModified().getTime()); 

represented by file.getRev() because this file is from dropbox API.

It's just a unique string representing a specific version (hence Versioned Rook) of the file in time.

If storage doesn't support it, you can just use file's modification time, as it's done for DirectoryRepo.
