Java V2 - Equvalent to V1 API's

[Joel T.9]

I'm looking for the following API's that exist in V1:

1) client.getDelta(deltaCursor)
2) client.createTemporaryDirectUrl(path)
3) client.disableAccessToken()

For the first one, getDelta, it appears this would be equivalent:
ListFolderResult result = client.files().listFolderContinue(deltaCursor);

However, I couldn't tell how to determine if an entry was deleted, the previous API I used DbxEntry.metadata == null.

For 2&3, maybe using the old API is supported still? The only reason I need the new API is to use the file ID support mostly for detecting file renames.

Quick follow up here for anyone looking who hasn't already seen it, the API v2 Java SDK does now have the equivalent of createTemporaryDirectUrl as getTemporaryLink.
