public class ZEllipse

extends ZShape

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.

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).

Parameters:

x - X-coord of top-left corner

y - Y-coord of top-left corner

ZEllipse

public ZEllipse(double x,
                double y,
                double width,
                double height)

Constructs and initializes an Ellipse2D from the specified coordinates.

Parameters:

x - X-coord of top-left corner

y - Y-coord of top-left corner

width - Width of ellipse

height - Height of ellipse

ZEllipse

public ZEllipse(java.awt.geom.Ellipse2D r)

Constructs a new Ellipse based on the geometry of the one passed in.

Parameters:

r - A ellipse to get the geometry from

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.

Parameters:

x - X coordinate of top-left corner.

y - Y coordinate of top-left corner.

width - Width of ellipse.

height - Height of ellipse.

setFrame

public void setFrame(java.awt.geom.Ellipse2D r)

Sets coords of ellipse

Parameters:

r - The new ellipse coordinates

getShape

public java.awt.Shape getShape()

Return the shape.

Overrides:

getShape in class ZShape

Returns:

the Shape.

setEllipse

public void setEllipse(java.awt.geom.Ellipse2D aEllipse)

Set the ellipse.

Parameters:

aEllipse - The new ellipse.

writeObject

public void writeObject(ZObjectOutputStream out)
                 throws java.io.IOException

Write out all of this object's state.

Overrides:

writeObject in class ZBasicVisualComponent

Parameters:

out - The stream that this object writes into

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.

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
