public class Polygon
extends AbstractColorableGraphic

A polygon is a Graphic that can form many shapes. To use, set the desired dimension of the polygon. Then add at least three points in order to correctly make a polygon. This will play connect the dots in the order that the points are added. Then connects the last point back to the first, forming a polygon.

Constructor Summary

Polygon()
Creates a new instance of Polygon with no vertices

Method Summary

void	actualPaint(Graphics2D gs, Point location, Dimension dimension) This method uses the Graphics2D object to paint the Polygon onto the container.
void	addPoint(Point p) Add a point to the polygon
Point	getLocation() Returns the location of the polygon
Shape	getShape() Gets a java.awt.shape that represents this shape
void	move(Vector v) Moves the Polygon by some amount, specified by a vector
void	removePoint(Point p) removes the first occurrence of point p from the polygon
void	setDimension(Dimension d) Resizes the Polygon to a specific dimension.
void	setLocation(Point point) Sets the location of the polygon.

Constructor Detail

Polygon

public Polygon()

Creates a new instance of Polygon with no vertices

Method Detail

addPoint

public void addPoint(Point p)

Add a point to the polygon

Parameters:

p - the point to add

removePoint

public void removePoint(Point p)

removes the first occurrence of point p from the polygon

Parameters:

p - The Point to remove

actualPaint

public void actualPaint(Graphics2D gs,
                        Point location,
                        Dimension dimension)

This method uses the Graphics2D object to paint the Polygon onto the container. The location and dimension parameters are not used because the polygon knows it's location and dimension

Parameters:

gs - The Graphics2D object to do the painting

location - Does nothing

dimension - Does Nothing

See Also:

Graphic.actualPaint(java.awt.Graphics2D, java.awt.Point, java.awt.Dimension)

setLocation

public void setLocation(Point point)

Sets the location of the polygon. TODO: does this do the upper left hand corner of the bounding box?

Specified by:

setLocation in interface Locatable

Overrides:

setLocation in class AbstractGraphic

Parameters:

point - A java.awt.Point representing the new location of the Polygon

See Also:

Locatable.setLocation(java.awt.Point)

getLocation

public Point getLocation()

Returns the location of the polygon

Specified by:

getLocation in interface Locatable

Overrides:

getLocation in class AbstractGraphic

Returns:

A java.awt.Point representing the location of the polygon

See Also:

AbstractGraphic.getLocation()

move

public void move(Vector v)

Moves the Polygon by some amount, specified by a vector

Specified by:

move in interface Locatable

Overrides:

move in class AbstractGraphic

Parameters:

v - The vector representing the amount to move the Polygon

See Also:

Locatable.move(cse115.utilities.Vector)

setDimension

public void setDimension(Dimension d)

Resizes the Polygon to a specific dimension. Warning: still in beta testing and will probably not function as expected.

Specified by:

setDimension in interface Sizeable

Overrides:

setDimension in class AbstractGraphic

Parameters:

d - The dimension which the polygon should have

See Also:

Sizeable.setDimension(java.awt.Dimension)

getShape

public Shape getShape()

Gets a java.awt.shape that represents this shape

Returns:

a java.awt.Polygon that represents this polygon

See Also:

Graphic.getShape()
