Please separate this into 2 PRs -- one for javadoc and one for autovalue. These are two separate features that should be judged independently.

@dhalperi I created #3113 - after that is merged I will modify this PR and resubmit...

hope that makes sense...

cheers

I was away last week so I couldn't follow this discussion, thanks @hepekhe for bringing this info (the documentation on how to make both IOs work with the google emulators).
One extra slightly related question. Have you tested the DatastoreIO with the Datastore emulator? (When I tried it didn't work, but I haven't checked recently).

[hepeknet]

Hi @dhalperi did not check DataStore - will do that today and let you know.

[hepeknet]

Closed - will submit new one containing only localhost options

Hi @iemejia I just tested DataStoreIO and it works with local emulator... at least basic reading and writing..using withLocalhost() does all the work... will play with it a bit

[iemejia]

Thanks a lot for checking that DataStoreIO works ok and for all the other contributions.
