Field Details

reset

public final boolean reset

If true, then you should reset your local state to be an empty folder before processing the list of delta entries.

This is always true for the first delta result, but for subsequent results it is true only in true rare situations. For example, if Dropbox changes their cursor format, or if a user asks Dropbox to completely reset his/her account, then the next time you call a delta API it may send down a reset and start you from scratch.

entries

public final List<DbxDelta.Entry<MD extends Dumpable>> entries

Apply these entries to your local state to catch up with the Dropbox server's state.

cursor

public final String cursor

A string that is used by the server to keep track of which entries have already been returned to you. This is what you pass in to the next API call to continue where you left off.

This cursor is valid for a long time. You'd typically store this somewhere persistent (such as a database) so you can resume continue you left off.

hasMore

public final boolean hasMore

If true, then there are more entries available. You can retrieve them immediately by making the call again (passing in cursor). If false, then wait at least 5 minutes before checking again.
