java.lang.Object
   |
   +----dnx.geom.Point2Set
public class Point2Set
extends Object
This implements a set of points in two dimensions. It is the parent class for polygons, planar graphs, and such.

Constructors

o Point2Set 
  public Point2Set()
o Point2Set 
  public Point2Set(Point2Set set)

Methods

o copy 
  public void copy(Point2Set set)
o clone 
  public Object clone()
Overrides:
clone in class Object
o invalidateCaches 
  protected void invalidateCaches()
o indexOfPointEql 
  public int indexOfPointEql(Point2 p)
o indexOfPointEqual 
  public int indexOfPointEqual(Point2 p)
o numberOfPoints 
  public final int numberOfPoints()
o getPoints 
  public Enumeration getPoints()
o getBoundingBox 
  public Rectangle2 getBoundingBox()
Return the bounding rectangle of the polygon. This specifies the minimum and maximum X and Y coordinates for the polygon.
o addPoint 
  public int addPoint(Point2 p)
add a point to a polygon. This does NOT copy the point; if the point is mutable, make sure to clone it first! Oh for a const keyword in Java ...
o addPoint 
  public int addPoint(float x,
                      float y)
o addPoint 
  public int addPoint(double x,
                      double y)
o deletePoint 
  public void deletePoint(int ind)
o deletePoints 
  public void deletePoints(int ind,
                           int count)
o translate 
  public void translate(float x,
                        float y)
o scale 
  public void scale(float xscale,
                    float yscale)
o scale 
  public void scale(float scale)
o reflectX 
  public void reflectX()
Reflect along the X axis.
o reflectY 
  public void reflectY()
Reflect along the Y axis.
o reflectXY 
  public void reflectXY()
Reflect along the line X = Y.
