Versioning support in Google Cloud Storage from Java? -


previously asked 1 question regarding building document management system on top of gae using google cloud storage document management system using google cloud storage. think got appropriate answers it. question extension of same. question is: can handle versioning through java code mention in link (developers.google.com/storage/docs/object-versioning) listing versions of object, retrieving specfic version of object etc.

since found list api's listing, deleting objects , doing several operations on google cloud storage can handle version through api's provided same java?

thanks in advance.

as google cloud storage doc states (https://developers.google.com/storage/docs/developer-guide) stored objects immutable.

i.e. can delete object after storing , store new one, same name.

so have versioning can organize data in pseudo folders. like: bucket/file-name/version-1; data/file-name/version-2 etc. need add bl handle versions (access recent 1 when needed, delete outdated, etc). however, in document management system think transactions, conflicts etc. want manage versions in db (on gae?) , store versions content in cloud files (i.e. named file content hashes).
