cfdm.Field.get_original_filenames

Field.get_original_filenames()

The names of files containing the original data and metadata.

The original files are those that contain some or all of the data and metadata when it was first instantiated, and are necessary (but perhaps not sufficient) to recreate the Field should the need arise. The cfdm.read function automatically records the original file names on all data that it creates.

The original files of any constituent components are also included.

In-place changes to the Field will not generally change the collection of original files. However if the Field was produced by combining other objects that also store their original file names, then the returned files will be the collection of original files from all contributing sources.

New in version (cfdm): 1.10.0.1

Returns

set

The original file names in normalised absolute form. If there are no original files then an empty set will be returned.
