process

suspend external fun process(data: Resource, options: GeoJsonDataSource.Companion.LoadOptions? = definedExternally): GeoJsonDataSource

update

external fun update(time: JulianDate): Boolean

Updates the data source to the provided time. This function is optional and is not required to be implemented. It is provided for data sources which retrieve data based on the current animation time or scene state. If implemented, update will be called by DataSourceDisplay once a frame.
