Method Detail

getNeighbors

public java.util.Vector getNeighbors(int x,
                                     int y,
                                     boolean returnNull)

Returns the ring of neighbors with a radius of 1 surrounding the cell at x, y.

Parameters:

x - the x coordinate of the cell

y - the y coordinate of the cell

Returns:

an array of doubles in clockwise order starting with the north or "12" neighboring cell

getNeighbors

public java.util.Vector getNeighbors(int x,
                                     int y,
                                     int[] extents,
                                     boolean returnNull)

Returns the rings of neighbors surrounding the cell at x, y. The number of rings is specified by the radius parameter.

Parameters:

x - the x coordinate of the cell

y - the y coordinate of the cell

extents - the number of neighbor rings to return

Returns:

an array of doubles beginning with the outermost ring of neighbors, starting with the north or "12 o'clock" neighboring cell, continuing clockwise and spiraling inwards

addXY

protected void addXY(java.util.Vector v,
                     int x,
                     int y)
