Constructor Detail

RingChartShape

public RingChartShape(java.awt.geom.Arc2D arc,
                      java.awt.geom.Rectangle2D drawArea,
                      java.lang.String text)

A constructor.

Parameters:

arc - Arc2D A arc shape (null not permitted).

drawArea - Rectangle2D The draw area (null not permitted).

text - String The text (null permitted).

Method Detail

getLengthFactor

public double getLengthFactor()

Returns the length factor.

Returns:

double The length factor.

setLengthFactor

public void setLengthFactor(double factor)

Sets the length factor and sends a ChartShapeChangeEvent to all registered listeners.

Parameters:

factor - double The length factor,in interval (0,1].

draw

public void draw(java.awt.Graphics2D g2)

Draw the ChartShape on a Java 2d graphics device(such as the screen or the printer). The shape's coordinate is ignored.

Specified by:

draw in interface IChartShape

Overrides:

draw in class SectorChartShape

Parameters:

g2 - Graphics2D The graphics device (such as the screen or the printer) (null not permitted).

getLockPoint

public java.awt.geom.Point2D getLockPoint()

Returns the lock coordinates of this shape.

Specified by:

getLockPoint in interface IChartShape

Overrides:

getLockPoint in class SectorChartShape

Returns:

Point2D The coordinate.

calculateTransformedShape

protected void calculateTransformedShape()

Calculate the transformed shape.

Overrides:

calculateTransformedShape in class SectorChartShape

getHotspotShape

protected java.awt.Shape getHotspotShape()

Returns the hotspot shape.

Overrides:

getHotspotShape in class SectorChartShape

Returns:

Shape The hotspot shape (maybe null).

getShapeType

public ShapeType getShapeType()

The type for describe this shape.

Specified by:

getShapeType in interface IChartShape

Overrides:

getShapeType in class SectorChartShape

Returns:

ShapeType The constant value in class ShapeType.

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class SectorChartShape

Returns:

int A hash code value for this object.

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class SectorChartShape

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Creates and returns a copy of this object.

Overrides:

clone in class SectorChartShape

Returns:

object a clone of this instance.

Throws:

java.lang.CloneNotSupportedException - if the object's class does not support the Cloneable interface. Subclasses that override the clone method can also throw this exception to indicate that an instance cannot be cloned.
