public static final class RasterDataSourceConfiguration.Provider extends Object

Configuration of a data provider.

  • Field Details

    • urlProvider

      @NonNull public TileUrlProviderCallback urlProvider

      Provides a function that generates URLs based on tile coordinates and storage level.

    • tilingScheme

      @NonNull public TilingScheme tilingScheme

      The tiling scheme used by this source.

    • storageLevels

      @NonNull public List<Integer> storageLevels

      The storage levels available for this data source. Supported range [0, 31]. At least one level must be available for this provider to be used as a source of data. At storage level zero, the whole world is represented by one tile. At storage level 1 the world is split in 2x2 tiles (or in 2x1 tiles, depending on the tiling scheme). The tiling process continues in this fashion until sufficient granularity has been achieved. In the XYZ addresing scheme for tiles, z value of the tile key coresponds to the storage level. Depending on the available storage levels and the given camera zoom level, the appropriate z value of the tile key will be determined.

    • hasAlphaChannel

      public boolean hasAlphaChannel

      A flag indicating whether the image content contains an alpha channel for transparency. Default value is false.

    • headers

      @Nullable public Map<String,String> headers

      The optional name-value pairs specifying HTTP headers that are passed with each tile request.

  • Constructor Details

    • Provider

      public Provider(@NonNull TileUrlProviderCallback urlProvider, @NonNull TilingScheme tilingScheme, @NonNull List<Integer> storageLevels, boolean hasAlphaChannel, @Nullable Map<String,String> headers)

      Creates a new instance.
