Interface Tile

All Superinterfaces:
Cloneable, Shareable
public interface Tile extends Cloneable, Shareable
This class represent a rectangular section (region) of a layer. It enable adding and retrieving elements associated with the layer. All tiles are part of a specific tile set (TileSet) which forms a grid to span the whole layer. Tiles are used divide in smaller region the layer to increase efficiency. When changes occurs only the corresponding tiles needs to be updated on the client side.
