public class ZEllipse

ZEllipse is a graphic object that represents a hard-cornered or rounded ellipse.

Warning: Serialized and ZSerialized objects of this class will not be compatible with future Jazz releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Jazz. A future release of Jazz will provide support for long term persistence.

Field Detail

ellipse

protected transient java.awt.geom.Ellipse2D ellipse
Constructor Detail

ZEllipse

public ZEllipse()
Constructs a new Ellipse, initialized to location (0, 0) and size (0, 0).

ZEllipse

public ZEllipse(double x,
                double y)
Constructs an Ellipse2D at the specified location, initialized to size (0, 0).

ZEllipse

public ZEllipse(double x,
                double y,
                double width,
                double height)
Constructs and initializes an Ellipse2D from the specified coordinates.

ZEllipse

public ZEllipse(java.awt.geom.Ellipse2D r)
Constructs a new Ellipse based on the geometry of the one passed in.

Method Detail

duplicateObject

protected java.lang.Object duplicateObject()
Returns a clone of this object.

Overrides:
duplicateObject in class ZBasicVisualComponent
See Also:
ZSceneGraphObject.duplicateObject()

getEllipse

public java.awt.geom.Ellipse2D getEllipse()
Return the ellipse.

Returns:
the Ellipse2D.

setFrame

public void setFrame(double x,
                     double y,
                     double width,
                     double height)
Sets the coordinates of this ellipse.

setFrame

public void setFrame(java.awt.geom.Ellipse2D r)
Sets coords of ellipse

getShape

public java.awt.Shape getShape()
Return the shape.

Specified by:
getShape in class ZShape
Returns:
the Shape.

setEllipse

public void setEllipse(java.awt.geom.Ellipse2D aEllipse)
Set the ellipse.

writeObject

public void writeObject(ZObjectOutputStream out)
                 throws java.io.IOException
Write out all of this object's state.

Specified by:
writeObject in interface ZSerializable
Overrides:
writeObject in class ZBasicVisualComponent
Parameters:
out - The stream that this object writes into
java.io.IOException

setState

public void setState(java.lang.String fieldType,
                     java.lang.String fieldName,
                     java.lang.Object fieldValue)
Set some state of this object as it gets read back in. After the object is created with its default no-arg constructor, this method will be called on the object once for each bit of state that was written out through calls to ZObjectOutputStream.writeState() within the writeObject method.

Specified by:
setState in interface ZSerializable
Overrides:
setState in class ZBasicVisualComponent
Parameters:
fieldType - The fully qualified type of the field
fieldName - The name of the field
fieldValue - The value of the field
