All Implemented Interfaces:

CustomGraphic, Locatable, Rotatable

Direct Known Subclasses:

Image, Shape, ShapeGroup

public abstract class AbstractShape
extends AbstractGraphic
implements Locatable, Rotatable

AbstractShape: an abstract superclass for Shape and ShapeGroup. Mostly for proper design hierarchy; it also means that a ShapeGroup can contain ShapeGroups. unh addition

Field Summary

protected double

_rot

Constructor Summary

AbstractShape()
Default constructor - does nothing but check that a Frame has been created! UNH addition: 11/14/09 rdb

Method Summary

boolean	boundsIntersects(AbstractShape s) Intersect the bounds of this object with the argument.
protected java.awt.Point	center() convenience method to get the center of Shape
protected static double	distance(java.awt.Point p1, java.awt.Point p2) convenience static method to compute distance between 2 points
abstract java.awt.Rectangle	getBounds()
java.awt.Point	getCenter() Returns the center of this Shape.
int	getCenterX() Returns the X-coordinate of this Shape's center.
int	getCenterY() Returns the Y-coordinate of this Shape's center.
abstract int	getHeight()
protected java.awt.Point	getIntersection(java.awt.Point start, double angle, AbstractShape s) getIntersection: get the intersection of the line starting at start with angle ( radians ) with the AbstractShape s Return the Point of intersection with the "wall" of the Frame if not found, or the point of intersection with the bounding box of s if found intersection() exploits this for shape-specific distances
abstract java.awt.Point	getLocation() Returns the object's location.
abstract int	getRotation() Returns the object's rotation in degrees.
abstract int	getWidth()
abstract int	getXLocation() Returns the object's x location.
abstract int	getYLocation() Returns the object's y location.
int	intersects(AbstractShape s) Generic AbstractShape handler Same as rectangle; exists for weird things that aren't the standard Shapes and for use in ShapeGroup's handler
int	intersects(ShapeGroup s) ShapeGroup intersection handler Calls intersects() for each AbstractShape in the group and returns the closest.
void	setCenter(java.awt.Point p) Moves this Shape so that its center is at p.
void	setLocation(int x, int y) Set object's location to given coordinates.
abstract void	setLocation(java.awt.Point p) Set object's location to given point.
abstract void	setRotation(int d) Sets the object's rotation in degrees.

Method Detail

setLocation

public void setLocation(int x,
                        int y)

Set object's location to given coordinates.

Specified by:

setLocation in interface Locatable

setLocation

public abstract void setLocation(java.awt.Point p)

Description copied from interface: Locatable

Set object's location to given point.

Specified by:

setLocation in interface Locatable

getBounds

public abstract java.awt.Rectangle getBounds()

getXLocation

public abstract int getXLocation()

Description copied from interface: Locatable

Returns the object's x location.

Specified by:

getXLocation in interface Locatable

getYLocation

public abstract int getYLocation()

Description copied from interface: Locatable

Returns the object's y location.

Specified by:

getYLocation in interface Locatable

getWidth

public abstract int getWidth()

getHeight

public abstract int getHeight()

getLocation

public abstract java.awt.Point getLocation()

Description copied from interface: Locatable

Returns the object's location.

Specified by:

getLocation in interface Locatable

setRotation

public abstract void setRotation(int d)

Description copied from interface: Rotatable

Sets the object's rotation in degrees.

Specified by:

setRotation in interface Rotatable

getRotation

public abstract int getRotation()

Description copied from interface: Rotatable

Returns the object's rotation in degrees.

Specified by:

getRotation in interface Rotatable

getCenter

public java.awt.Point getCenter()

Returns the center of this Shape. unh addition

setCenter

public void setCenter(java.awt.Point p)

Moves this Shape so that its center is at p. unh addition

getCenterX

public int getCenterX()

Returns the X-coordinate of this Shape's center.

getCenterY

public int getCenterY()

Returns the Y-coordinate of this Shape's center.

boundsIntersects

public boolean boundsIntersects(AbstractShape s)

Intersect the bounds of this object with the argument. Returns true if there is overlap. The intersects method should do this, except for Line. unh addition 11/02/08 rdb: created

intersects

public int intersects(AbstractShape s)

Generic AbstractShape handler Same as rectangle; exists for weird things that aren't the standard Shapes and for use in ShapeGroup's handler

intersects

public int intersects(ShapeGroup s)

ShapeGroup intersection handler Calls intersects() for each AbstractShape in the group and returns the closest.

getIntersection

protected java.awt.Point getIntersection(java.awt.Point start,
                                         double angle,
                                         AbstractShape s)

getIntersection: get the intersection of the line starting at start with angle ( radians ) with the AbstractShape s Return the Point of intersection with the "wall" of the Frame if not found, or the point of intersection with the bounding box of s if found intersection() exploits this for shape-specific distances

distance

protected static final double distance(java.awt.Point p1,
                                       java.awt.Point p2)

convenience static method to compute distance between 2 points

center

protected final java.awt.Point center()

convenience method to get the center of Shape
