Constructor Detail

GridSystem

public GridSystem()

GridSystem

public GridSystem(double originX,
          double originY,
          double width,
          double height)

Method Detail

addLevel

public void addLevel(int columns,
            int rows)

cellContaining

public int[] cellContaining(double x,
                   double y)

Returns an array of numbers describing the cell with the given XY. Each number in the array is for the next finer gridding - cell[0] is the number of the cell of the top-level grid, cell[1] for its subgrid, cell[2] for cell[1]'s subgrid, etc. The numbers start at zero for the top left cell and go from left to right, top to bottom just like written English. For example:

0	1	2
3	4	5
6	7	8

If the coordinate is outside the grid, returns null so be careful.
