var errorEvent: DefaultEvent

Gets an event that will be raised if an error is encountered during processing.

isLoading

var isLoading: Boolean

Gets a value indicating if the data source is currently loading data.

loadingEvent

var loadingEvent: DefaultEvent

loadAsync

fun loadAsync(data: Resource, options: GeoJsonDataSource.Companion.LoadOptions? = definedExternally): Promise<GeoJsonDataSource>

fun loadAsync(data: Any, options: GeoJsonDataSource.Companion.LoadOptions? = definedExternally): Promise<GeoJsonDataSource>

fun loadAsync(data: String, options: GeoJsonDataSource.Companion.LoadOptions? = definedExternally): Promise<GeoJsonDataSource>

process

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

Asynchronously loads the provided GeoJSON or TopoJSON data, without replacing any existing data.

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

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

fun processAsync(data: String, options: GeoJsonDataSource.Companion.LoadOptions? = definedExternally): Promise<GeoJsonDataSource>

update

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.
