__init__(limit: int = 0, lat_min: float | None = None, lat_max: float | None = None, lon_min: float | None = None, lon_max: float | None = None) → None

Initialize query with optional arguments

Parameters:

• limit (int, optional) – maximum number of states to get (0=all). Defaults to 0.

• lat_max (float, optional) – maximum latitude. Defaults to None.

• lon_min (float, optional) – minimum longitude. Defaults to None.

• lon_max (float, optional) – maximum longitude. Defaults to None.

list[MapState]

async from_server(table: str, db: DatabaseManager) → list[MapState]

Query a list of states from server database

Parameters:

• table (str) – name of database table

• db (DatabaseManager) – database manager instance

Returns:

selected list of simple map states

Return type:

list[MapState]

parse_table_row(raw_entry: tuple) → MapState

Parse raw table data into a simple map state

Parameters:

raw_entry (tuple) – raw table data

Returns:

corresponding simple map state
