__init__(supply_database_path)

dump(folder_name)

Creates a folder and dumps all tables in the database to CSV files

from_gmns(gmns_folder, crs)

Imports the network data from the GMNS format

restore(folder_name[, jumpstart])

Reloads the network from a previous dump to csv

to_gmns(gmns_folder, crs)

__init__(supply_database_path: PathLike)#
dump(folder_name: str) → None#

Creates a folder and dumps all tables in the database to CSV files

Args:

folder_name (str): Folder where the dump files are to be placed
