public class ZLine

extends ZShape

ZLine is a simple ZShape implementation that uses a Line2D as the underlying shape model.

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.

Method Detail

duplicateObject

protected java.lang.Object duplicateObject()

Returns a clone of this object.

Overrides:

duplicateObject in class ZBasicVisualComponent

See Also:

ZSceneGraphObject.duplicateObject()

getLine

public java.awt.geom.Line2D getLine()

Return the line.

getShape

public java.awt.Shape getShape()

Return the current shape.

Overrides:

getShape in class ZShape

setLine

public void setLine(java.awt.geom.Line2D aLine)

Set the line.

setLine

public void setLine(java.awt.geom.Point2D pt1,
                    java.awt.geom.Point2D pt2)

Set the line.

setLine

public void setLine(double x1,
                    double y1,
                    double x2,
                    double y2)

Set the line.

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
