com.github.basking2.sdsai.marchinesquares.Side

Direct Known Subclasses:

Side.ArtificialSide

public class Side
extends Object

A side is one cell value and optionally one or two points on the edge of a Tile. Points are assigned as either a begin or end point. That is, what role does that point play in the contour of the cell of the tile the side is describing.

Field Details

cell

public byte cell

The value in the data grid. This is -1, 0, or 1. This is used to construct contours with neighboring tiles.

beginPoint

public LinkedList.Node<Point> beginPoint

A point that begins a contour in a particular cell. Its next field should be defined. The endPoint of one side should be linked to the beginPoint of another side in the same cell.

endPoint

public LinkedList.Node<Point> endPoint

A point that ends a contour. Its next field will be empty if only a single cell is contoured. The endPoint of one side should be linked to the beginPoint of another side.

BOGUS_VALUE

public static byte BOGUS_VALUE

This is used to construct artificial sides as place holders.

Constructor Details

Side

public Side(byte cell,
 LinkedList.Node<Point> beginPoint,
 LinkedList.Node<Point> endPoint)

Constructor.

Parameters:

cell - A cell value.

beginPoint - A point of a line.

endPoint - A point of a line.

Side

public Side(byte cell)

Constructor.

Parameters:

cell - A cell value.

Method Details

toString

public String toString()

Overrides:

toString in class Object

setPoints

public void setPoints(double x,
 double y,
 byte side,
 byte color,
 byte left,
 byte right)

buildArtificialSide

public static Side buildArtificialSide(double x,
 double y,
 byte side,
 byte color,
 byte left,
 byte right)

Build an artificial side with the correct number of points.

Parameters:

x - The x value to create points at.

y - The y value to create points at.

side - The side of a cell that this lies on. The values are 0 is the top, 1 is the right, 2 is the bottom, and 3 is the left.

color - The color to set the linked list nodes to.

left - The value of the point that is on the left of the side, the side being viewed from the center of the cell. The counter-clockwise most point.

right - The value of the point that is on the right of the side, the side being viewed from the center of the cell. The clockwise most point.

Returns:

A built artificial side.

swapPoints

public void swapPoints()

prettyPrint

public String prettyPrint()
