Overview

This class is part of a private API. This class may only be used in the Homebrew/brew repository. Third parties should avoid using this class if possible, as it may be removed or changed without warning.

Remembers which files have already been checksum-verified in this process, so the same unchanged file is not hashed once per download object that references it.
