Class AssetTileDataSource

java.lang.Object

com.nutiteq.datasources.TileDataSource

com.nutiteq.datasources.AssetTileDataSource

public class AssetTileDataSource
extends TileDataSource

A tile data source where each map tile is a seperate image file bundled with the application.
The requests are generated using a template scheme, where tags in the basePath string are replaced with actual values.
The following tags are supported: zoom, x, y, xflipped, yflipped, quadkey.

For example, if basePath = "t{zoom}_{x}_{y}.png" and the requested tile has zoom == 2,
x == 1 and y == 3, then the tile will be loaded from the following path: "t2_1_2.png".
