POE::Component::DirWatch::Role::Signatures is a role which provides File::Signature functionality to DirWatch-based classes. It will keep a hashref of signatures of the files processing to allow you to determine if a file has changed.
Read-write. Will return a hashref in which keys will be the full path of the files seen and the value will be a stringified File::Signature object.
after '_file_callback' Add the file's signature to
signatures if it doesnt yet exist.
before '_poll' the list of known files is checked and if any of the files no longer exist they are removed from the list of known files.
