Method Detail

draw

public void draw(java.awt.Graphics2D g2)

Description copied from interface: Node

Draw the node.

Specified by:

draw in interface Node

Overrides:

draw in class AbstractNode

Parameters:

g2 - the graphics context

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

getConnectionPoint

public java.awt.geom.Point2D getConnectionPoint(Direction d)

Description copied from interface: Node

Get the best connection point to connect this node with another node. This should be a point on the boundary of the shape of this node.

Parameters:

d - the direction from the center of the bounding rectangle towards the boundary

Returns:

the recommended connection point
