Class DemoTileSource

java.lang.Object
com.codename1.maps.vector.DemoTileSource
All Implemented Interfaces:
TileSource
public final class DemoTileSource extends Object implements TileSource
A self-contained TileSource that synthesizes a deterministic Mapbox Vector Tile in memory for every address, with no network or bundled assets. Every tile carries the same recognizable content -- a water body, a landuse area, two roads, a building and a labeled place -- which makes it ideal for offline demos and for reproducible map screenshot tests.

    Method
    Description
    static byte[]
    buildTile()
    Builds the synthetic MVT payload.
    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

    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.
