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 Summary

Modifier and Type	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	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.

Method Details

isVector

public boolean isVector()

True for MVT vector tiles, false for raster image tiles.

Specified by:

isVector in interface TileSource

getTileSize

public int getTileSize()

The tile edge in pixels (almost always 256).

Specified by:

getTileSize in interface TileSource

getMinZoom

public int getMinZoom()

The smallest zoom level this source serves.

Specified by:

getMinZoom in interface TileSource

getMaxZoom

public int getMaxZoom()

The largest zoom level this source serves.

Specified by:

getMaxZoom in interface TileSource

getAttribution

public String getAttribution()

Attribution text that must be displayed over the map.

Specified by:

getAttribution in interface TileSource

fetchTile

public 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.

Specified by:

fetchTile in interface TileSource

buildTile

public static byte[] buildTile()
                        throws IOException

Builds the synthetic MVT payload. Public and static so unit tests and the demo can reuse exactly the same bytes.

Throws:

IOException
