Attributes Documentation

formatter

A Formatter class or fully-qualified name.

path

Path to the dataset (str).

If the dataset was exported with transfer=None (i.e. in-place), this is relative to the datastore root (only datastores that have a well-defined root in the local filesystem can be expected to support in-place exports). Otherwise this is relative to the directory passed to Datastore.export.
