com.geoway.mobile.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".

AssetTileDataSource

public AssetTileDataSource(long cPtr,
                           boolean cMemoryOwn)

AssetTileDataSource

public AssetTileDataSource(int minZoom,
                           int maxZoom,
                           java.lang.String basePath)

Constructs an AssetTileDataSource object.

参数:

minZoom - The minimum zoom level supported by this data source.

maxZoom - The maximum zoom level supported by this data source.

basePath - The base path containing tags (for example, "t{zoom}_{x}_{y}.png").

参数:

tile - The tile to load.

返回:

The tile data. If the tile is not available, null may be returned.

buildAssetPath

protected java.lang.String buildAssetPath(java.lang.String basePath,

swigGetDirectorObject

public java.lang.Object swigGetDirectorObject()

Returns the connected director object. This is used internally by the SDK.

覆盖:

swigGetDirectorObject 在类中 TileDataSource

返回:

The connected director object or null if director is not connected.
