Class CustomGeometrySource

java.lang.Object

com.dingi.dingisdk.style.sources.Source

com.dingi.dingisdk.style.sources.CustomGeometrySource

public class CustomGeometrySource
extends 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.

CustomGeometrySource

@UiThread
public CustomGeometrySource(java.lang.String id,
                                      CustomGeometrySourceOptions options,
                                      GeometryTileProvider provider)

Create a CustomGeometrySource with non-default CustomGeometrySourceOptions.

Parameters:

id - The source id.

options - CustomGeometrySourceOptions.

provider - The tile provider that returns geometry data for this source.

Method Detail

invalidateRegion

public void invalidateRegion(LatLngBounds bounds)

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.

Parameters:

bounds - The region in which features should be invalidated at all zoom levels

invalidateTile

public void invalidateTile(int zoomLevel,
                           int x,
                           int y)

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

Parameters:

zoomLevel - Tile zoom level.

x - Tile X coordinate.

y - Tile Y coordinate.

setTileData

public void setTileData(int zoomLevel,
                        int x,
                        int y,
                        com.mapbox.geojson.FeatureCollection data)

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.

Parameters:

zoomLevel - Tile zoom level.

x - Tile X coordinate.

y - Tile Y coordinate.

data - Feature collection for the tile.

querySourceFeatures

@NonNull
public java.util.List<com.mapbox.geojson.Feature> querySourceFeatures(@Nullable
                                                                               Expression filter)

Queries the source for features.

Parameters:

filter - an optional filter expression to filter the returned Features

Returns:

the features

initialize

protected void initialize(java.lang.String sourceId,
                          java.lang.Object options)

finalize

protected void finalize()
                 throws java.lang.Throwable

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable
