Class PathEnd

java.lang.Object
  maze.filler.PathEnd

public class PathEnd

extends java.lang.Object

A Bean that represents the end cell of a path being generated. These are pushed into PushPop storage structures to track the various branches of the path through the maze as the path is being constructed.

Field Summary

protected Coordinate	theCoordinate The Coordinate for the end of the path.
protected int	theDirection The direction of the end of the path.
protected MazeGeometry	theGeometry Contains the MazeGeometry required to interpret this PathEnd.

Constructor Summary

PathEnd(MazeGeometry g, Coordinate c, int d)
Creates a new PathEnd from a Coordinate and a direction.

Method Summary

Coordinate	coord() Returns the Coordinate for the end of the path.
int	dir() Returns the current direction.
Coordinate	getCoordinate() Gets the coordinate of the path end cell.
int	getDirection() Gets the direction this path end is facing.
void	setCoordinate(Coordinate c) Sets the coordinate for this path end cell.
void	setDirection(int d) Sets the direction this path end is facing.
void	setGeometry(MazeGeometry g) Sets the underlying Maze Geometry for this PathEnd.
java.lang.String	toString() Returns a String representation for the end of the path.
