public class XPolygon
extends Polygon
Extended polygon with following changes:
1. getBBox() returns bounding box 1 pixel wider&higher than getBounds()
2. contains() returns true for edge points
3. Noet that deprecated methods in Polygon can't be used

Constructor Index

o XPolygon()
o XPolygon(int[], int[], int)
o XPolygon(Polygon)

Method Index

o addPoint(int, int)
o contains(int, int)
o contains(Point)
o contains(XPolygon)
Test if contains the given poly
Note the function returns false when the given polygon has common vertices with the first one
o getBBox()
o scale(double)
scale the polygon
o setPoint(int, int, int)
o translate(int, int)

Constructors

o XPolygon 
 public XPolygon()
o XPolygon 
 public XPolygon(int x[],
                 int y[],
                 int n)
o XPolygon 
 public XPolygon(Polygon p)

Methods

o scale 
 public final void scale(double s)
scale the polygon

Parameters:
scale - the scale (must be >0)
o contains 
 public final boolean contains(int x,
                               int y)
Overrides:
contains in class Polygon
o contains 
 public final boolean contains(Point p)
Overrides:
contains in class Polygon
o contains 
 public final boolean contains(XPolygon f)
Test if contains the given poly
Note the function returns false when the given polygon has common vertices with the first one

Parameters:
f - the second polygon
o getBBox 
 public final Rectangle getBBox()

                            int y)
Overrides:
addPoint in class Polygon
o setPoint 
 public final void setPoint(int i,
                            int x,
                            int y)
o translate 
 public final void translate(int x,
                             int y)
Overrides:
translate in class Polygon
