Examples of org.geomajas.layer.tile.TileCode

org.geomajas.layer.tile.TileCode
A unique spatial code determining the location of a tile. It implements the Serializable interface as it is often used as a data transfer object.

Tiling mechanisms are usually build in several levels, where the top level has only one tile, and for each level that you go deeper, the number of tiles doubles in both the X and the Y directions. All 3 parameters (tileLevel, X and Y) must always be positive integers.

Note that at a certain tile level, X and Y must always be a value between 0 and (2^tileLevel) - 1. For example:
- Tile level = 0: X=0, Y=0
- Tile level = 1: X=[0, 1], Y=[0, 1]
- Tile level = 2: X=[0, 3], Y=[0, 3]
- Tile level = 3: X=[0, 7], Y=[0, 7]
- Tile level = N: X=[0, (2^N) - 1], Y=[0, (2^N) - 1]
