Interface TileSource

All Known Implementing Classes:
BundledTileSource, DemoTileSource, HttpTileSource, MvtTileSource, RasterTileSource
public interface TileSource
Supplies tile payloads to the VectorMapEngine given a slippy-map z/x/y address. Two flavors exist: vector sources (isVector() true) returning MVT protobuf bytes that the engine decodes and styles, and raster sources returning encoded-image bytes that the engine simply blits. The bundled BundledTileSource, the networked MvtTileSource and the keyless RasterTileSource cover the universal, vector and zero-config cases respectively.

  • Method Summary

    Modifier and Type
    Method
    Description
    void
    fetchTile(int z, int x, int y, TileCallback callback)
    Requests the tile at z/x/y, delivering the result to callback on the event dispatch thread.
    String
    getAttribution()
    Attribution text that must be displayed over the map.
    int
    getMaxZoom()
    The largest zoom level this source serves.
    int
    getMinZoom()
    The smallest zoom level this source serves.
    int
    getTileSize()
    The tile edge in pixels (almost always 256).
    boolean
    isVector()
    True for MVT vector tiles, false for raster image tiles.
