update_type: ClassVar[str] = 'update_n_dia_sources'

Class variable defining type of the update, must be defined in all concrete subclasses and be unique.

Methods Documentation

classmethod from_json(update_time_ns: int, update_order: int, json_str: str) → ApdbUpdateRecord

classmethod from_named_tuple(named_tuple: Any) → DiaObjectId

Construct DiaObjectId from a named tuple.

Parameters:

named_tuple

Named tuple which includes the same attributes as this class, e.g. a tuple returned from pandas.DataFrame.itertuples(). Any additional attributes are ignored.
