*Callable[[DataCoordinate], bool] | predicate | ||
) |
Process a directory. Parameters ---------- path : `str` Full path to the directory to be processed. datasets : `dict` [`DatasetType`, `list` ] Dictionary that found datasets should be added to. Nested lists elements are tuples of `FileDataset` and an optional "CALIBDATE" `str` value (for calibration datasets only). predicate : `~collections.abc.Callable` A callable taking a single `DataCoordinate` argument and returning `bool`, indicating whether that (Gen3) data ID represents one that should be included in the scan.
