Method Detail

getTile

public Tile getTile(int x,
                    int y)

Delegates to TileFactory.createTile(int, int), but implements a memory sensitive tile cache and if the tile has been previously created and is still in the cache, returns the cached tile. If the tile is currently being created on another thread, this method blocks until that is done.

This method is thread safe (if the underlying tile factory is).

Specified by:

getTile in interface TileProvider

Parameters:

x - The X coordinate of the tile to get.

y - The Y coordinate of the tile to get.

Returns:

The tile at the specified coordinates.
