=head1 NAME
POE::Component::DirWatch::WithCaller - Identical to POE::Component::DirWatch, but &filter and &(file,dir)_callback will be called with the name of the originating event. Will optionally also filter previously-seen files.
=head1 VERSION
1.0.0
=head1 FILTERING PREVIOUSLY-SEEN FILES
Depending on use case, it may be beneficial or necessary to filter out previously-seen files, either for performance reasons when monitoring highly populous directories for specific files, or for avoiding reprocessing files in the event that they are left in the directory after initial processing.
In this case, simply specifying C<ignore_seen =E<gt> 1> as a named argument when creating the DirWatch::WithCaller object will enable this behaviour.
While testing this feature, however, it was observed that some edge cases exist in which a file will be considered 'seen' when it has not been processed despite matching a defined monitor. To account for this, each file that has been considered 'seen' will be reprocessed once around 120 seconds after it was first 'seen'. This behaviour may not be desirable, and as such is disabled by default, and can be enabled by specifying C<ensure_seen =E<gt> 1> when creating the object.
