```
  - TileDataSource
```
protected TileDataSource()
```
    Constructs an abstract TileDataSource object.
    Note: EPSG3857 projection is used. minZoom is defined to be 0, maxZoom is defined to be 24.
  - TileDataSource
```
protected TileDataSource(int minZoom,
                         int maxZoom)
```
    Constructs an abstract TileDataSource object.
    Note: EPSG3857 projection is used.
    
    参数:
    
    minZoom - The minimum zoom level supported by this data source.
    
    maxZoom - The maximum zoom level supported by this data source.

```
    Creates a polymorphic instance of the given native object. This is used internally by the SDK.
    
    参数:
    
    cPtr - The native pointer of the instance.
    
    cMemoryOwn - The ownership flag.
    
    返回:
    
    The created instance.
  - getMinZoom
```
public int getMinZoom()
```
    Returns the minimum zoom level supported by this data source.
    
    返回:
    
    The minimum zoom level supported (inclusive).
  - getMaxZoom
```
public int getMaxZoom()
```
    Returns the maximum zoom level supported by this data source.
    
    返回:
    
    The maximum zoom level supported (exclusive).
  - getProjection
```
public Projection getProjection()
```
    Returns the projection of this tile source.
    
    返回:
    
    The projection of this tile source.
  - setTileSize
```
public void setTileSize(int size)
```
    设置瓦片大小，规则为256的倍数
  - getTileSize
```
public int getTileSize()
```
    获取瓦片大小
    
    返回:
    
    The projection of this tile source.
  - loadTile
```
public TileData loadTile(MapTile tile)
```
    Loads the specified tile.
    Note: the tile coordinate system used here is vertically flipped relative to layer tile coordinate system.
    
    参数:
    
    tile - The tile to load.
    
    返回:
    
    The tile data. If the tile is not available, null may be returned.
  - notifyTilesChanged
```
public void notifyTilesChanged(boolean removeTiles)
```
    Notifies listeners that the tiles have changed. Action taken depends on the implementation of the
    listeners, but generally all cached tiles will be reloaded. If the removeTiles flag is set all caches will be cleared
    prior to reloading, if it's not set then the reloaded tiles will replace the old tiles in caches as they finish loading.
    
    参数:
    
    removeTiles - The remove tiles flag.
  - isIntervalLevel
```
public boolean isIntervalLevel()
```
  - setIntervalLevel
```
public void setIntervalLevel(boolean value)
```
  - setDataBounds
```
public void setDataBounds(MapBounds dataBounds)
```
  - getDataBounds
```
public MapBounds getDataBounds()
```
  - swigGetClassName
```
public java.lang.String swigGetClassName()
```
    Returns the actual class name of this object. This is used internally by the SDK.
    
    返回:
    
    The class name of this object.
  - swigGetDirectorObject
```
public java.lang.Object swigGetDirectorObject()
```
    Returns the connected director object. This is used internally by the SDK.
    
    返回:
    
    The connected director object or null if director is not connected.
