CustomGeometrySource

class CustomGeometrySource @UiThread constructor(id: String?, options: CustomGeometrySourceOptions?, provider: GeometryTileProvider?) : Source(source)

Custom Vector Source, allows using FeatureCollections.

CustomGeometrySource uses a coalescing model for frequent data updates targeting the same tile id, which means, that the in-progress request as well as the last scheduled request are guaranteed to finish. Any requests scheduled meanwhile can be canceled.

Functions

invalidateRegion

fun invalidateRegion(bounds: LatLngBounds)

Invalidate previously provided features within a given bounds at all zoom levels. Invoking this method will result in new requests to GeometryTileProvider for regions that contain, include, or intersect with the provided bounds.

invalidateTile

fun invalidateTile(zoomLevel: Int, x: Int, y: Int)

Invalidate the geometry contents of a specific tile. Invoking this method will result in new requests to GeometryTileProvider for visible tiles.

querySourceFeatures

fun querySourceFeatures(filter: Expression?): List<Feature>

Queries the source for features.

setDetached

open fun setDetached()

setTileData

fun setTileData(zoomLevel: Int, x: Int, y: Int, data: FeatureCollection)

Set or update geometry contents of a specific tile. Use this method to update tiles for which GeometryTileProvider was previously invoked. This method can be called from background threads.
