armi.bookkeeping.db.factory module

armi.bookkeeping.db.factory.databaseFactory(dbName: str, permission: str, version: Optional[str] = None)

Return an appropriate object for interacting with a database file.

Parameters:

• dbName (str) – Path to db file, e.g. baseCase.h5

• permission (str) – String defining permission, r for read only. See armi.bookeeping.db.permissions

• version (str, optional) – Version of database you want to read or write. In most cases ARMI will auto-detect. For advanced users.

Notes

This is not a proper factory, as the different database versions do not present a common interface. However, this is useful code, since it at least creates an object based on some knowledge of how to probe around. This allows client code to just interrogate the type of the returned object to figure out to do based on whatever it needs.
