to_datafilelist

ndmapper.utils.to_datafilelist(arg, mode=None)

Derive a DataFileList object from one or a sequence of objects than can be converted to filename strings (eg. str, FileName or DataFile). The mode defaults to 'read' when given one or more filenames and to the existing mode for DataFile and DataFileList. Where all of the inputs are existing DataFile instances, those are re-used by reference (mode permitting), instead of opening new copies.

Beware of feeding this inappropriate argument types, as almost anything can be converted to str...
