Class CircleGeometry

java.lang.Object

diva.canvas.interactor.CircleGeometry

All Implemented Interfaces:

Geometry

public class CircleGeometry
extends java.lang.Object
implements Geometry

A class that provides support for manipulating the bounds of a figure. Because this geometry only provides one site at the bounds of the figure, and transforms the bounds equally in all directions, it makes sense to only use this Geometry type for figures containing circular shapes or otherwise highly-symmetric shapes.

Constructor Detail

CircleGeometry

public CircleGeometry(Figure figure,
                      java.awt.geom.Rectangle2D bounds)

Create a new geometry object on the given figure and with the given initial bounds.

Method Detail

getSite

public Site getSite(int id)

Get the single site with the given ID.

getMinimumSize

public double getMinimumSize()

Get the minimum size of the rectangle.

getN

public Site getN()

Get the north site (only site).

getFigure

public Figure getFigure()

Get the figure to which this geometry object is attached. Returns null if there isn't one.

Specified by:

getFigure in interface Geometry

getShape

public java.awt.Shape getShape()

Get the current shape that defines this geometry

Specified by:

getShape in interface Geometry

getBounds

public java.awt.geom.Rectangle2D getBounds()

Get the current rectangle that defines this geometry. This returns the same shape as getShape(), but as a Rectangle2D type.

setMinimumSize

public void setMinimumSize(double minimumSize)

Set the minimum size of the rectangle. The default is 1.0.

setShape

public void setShape(java.awt.Shape shape)

Set the shape that defines this geometry object. The shape must be a Rectangle2D, or an exception will be thrown.

Specified by:

setShape in interface Geometry

setBounds

public void setBounds(java.awt.geom.Rectangle2D rect)

Set the rectangle that defines this geometry object. This is the same as setShape(), but does not need to perform the type check.

sites

public java.util.Iterator sites()

Return an iteration over the sites in this geometry object.

translate

public void translate(double x,
                      double y)

Translate the geometry object

Specified by:

translate in interface Geometry
