LocationFactory

class lsst.daf.butler.LocationFactory(datastoreRoot: Union[lsst.daf.butler.core._butlerUri._butlerUri.ButlerURI, str])

Bases: object

Factory for Location instances.

The factory is constructed from the root location of the datastore. This location can be a path on the file system (absolute or relative) or as a URI.

Parameters:

datastoreRoot : str

Root location of the Datastore either as a path in the local filesystem or as a URI. File scheme URIs can be used. If a local filesystem path is used without URI scheme, it will be converted to an absolute path and any home directory indicators expanded. If a file scheme is used with a relative path, the path will be treated as a posixpath but then converted to an absolute path.
