Method Detail

getTilePositions

public static List<TilePosition> getTilePositions(BoundingBox boundingBox,
                                  byte zoomLevel,
                                  Point topLeftPoint,
                                  int tileSize)

getTiles

public static Set<Tile> getTiles(BoundingBox boundingBox,
                 byte zoomLevel,
                 int tileSize)

collisionFreeOrdered

public static List<MapElementContainer> collisionFreeOrdered(List<MapElementContainer> input)

Transforms a list of MapElements, orders it and removes those elements that overlap. This operation is useful for an early elimination of elements in a list that will never be drawn because they overlap.

Parameters:

input - list of MapElements

Returns:

collision-free, ordered list, a subset of the input.
