Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Class for post file data. This is mostly an abstraction to have data structures in a more Ruby like nature. This class just holds an adapted version of #save!, to handle the case of preview images having a different MD5 hash sum attribute than they actually should have. That is an e621 issue though.
