构造器详细资料

AbstractTileFactory

public AbstractTileFactory(TileFactoryInfo info)

Creates a new instance of DefaultTileFactory using the spcified TileFactoryInfo

参数:

info - a TileFactoryInfo to configure this TileFactory

方法详细资料

getTile

public Tile getTile(int x,
                    int y,
                    int zoom)

Returns the tile that is located at the given tilePoint for this zoom. For example, if getMapSize() returns 10x20 for this zoom, and the tilePoint is (3,5), then the appropriate tile will be located and returned.

指定者:

getTile 在类中 TileFactory

参数:

x - X index

y - Y index

zoom - Zoom value

返回:

Tile

getTileCache

public TileCache getTileCache()

setTileCache

public void setTileCache(TileCache cache)

getService

protected ExecutorService getService()

Subclasses may override this method to provide their own executor services. This method will be called each time a tile needs to be loaded. Implementations should cache the ExecutorService when possible.

返回:

ExecutorService to load tiles with

setThreadPoolSize

public void setThreadPoolSize(int size)

Set the number of threads to use for loading the tiles. This controls the number of threads used by the ExecutorService returned from getService(). Note, this method should be called before loading the first tile. Calls after the first tile are loaded will have no effect by default.

参数:

size -

startLoading

protected void startLoading(Tile tile)

从类复制的说明: TileFactory

Override this method to load the tile using, for example, an ExecutorService.

指定者:

startLoading 在类中 TileFactory

参数:

tile - The tile to load.

load

public void load(Tile tile)

指定者:

load 在类中 TileFactory

getURI

protected URI getURI(Tile tile)
              throws URISyntaxException

Gets the full URI of a tile.

参数:

tile -

返回:

URI

抛出:

URISyntaxException

createTileRunner

protected Runnable createTileRunner(Tile tile)

Subclasses can override this if they need custom TileRunners for some reason

参数:

tile - Tile

返回:

Runnable

promote

public void promote(Tile tile)

Increase the priority of this tile so it will be loaded sooner.

参数:

tile - Tile
