public abstract class OfflineTileFactory<T>

Copied some code from AbstractTileFactory, so I can use own TileRunner, which does all the reading and writing to the cache

Method Detail

getTile

public Tile<T> getTile(int x,
                       int y,
                       int zoom)

Description copied from class: AbstractTileFactory

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.

Overrides:

getTile in class AbstractTileFactory<T,Tile<T>>

zoom - the current zoom level

Returns:

the tile that is located at the given tilePoint for this zoom level. For example, if getMapSize() returns 10x20 for this zoom, and the tilePoint is (3,5), then the appropriate tile will be located and returned. This method must not return null. However, it can return dummy tiles that contain no data if it wants. This is appropriate, for example, for tiles which are outside of the bounds of the map and if the factory doesn't implement wrapping.

createOfflineTile

protected abstract Tile<T> createOfflineTile(int tileX,
                                             int tileY,
                                             int zoom,
                                             String url)

Method for creating offline Tile

Parameters:

tileX - x coordinates

tileY - y coordinates

zoom - zoom level

url - tile url

Returns:

created offline tile
