Method Detail

clone

public java.lang.Object clone()

Specified by:

clone in interface Node

Overrides:

clone in class AbstractNode

translate

public void translate(double dx,
                      double dy)

Description copied from interface: Node

Translates the node by a given amount

Specified by:

translate in interface Node

Overrides:

translate in class AbstractNode

Parameters:

dx - the amount to translate in the x-direction

dy - the amount to translate in the y-direction

contains

public boolean contains(java.awt.geom.Point2D p)

Description copied from interface: Node

Tests whether the node contains a point.

Parameters:

p - the point to test

Returns:

true if this node contains aPoint

getBounds

public java.awt.geom.Rectangle2D getBounds()

Description copied from interface: Node

Get the bounding rectangle of the shape of this node

Returns:

the bounding rectangle

setBounds

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