Class HyperbolicShapeTransformer

java.lang.Object

org.jungrapht.visualization.transform.MutableTransformerDecorator

org.jungrapht.visualization.transform.LensTransformer

org.jungrapht.visualization.transform.HyperbolicTransformer

org.jungrapht.visualization.transform.shape.HyperbolicShapeTransformer

All Implemented Interfaces:

BidirectionalTransformer, MutableTransformer, ShapeFlatnessTransformer, ShapeTransformer, ChangeEventSupport

public class HyperbolicShapeTransformer
extends HyperbolicTransformer
implements ShapeFlatnessTransformer

HyperbolicShapeTransformer extends HyperbolicTransformer and adds implementations for methods in ShapeFlatnessTransformer. It modifies the shapes (Vertex, Edge, and Arrowheads) so that they are distorted by the hyperbolic transformation

HyperbolicShapeTransformer

protected HyperbolicShapeTransformer(Lens lens,
                                     MutableTransformer delegate)

Create an instance, setting values from the passed component and registering to listen for layoutSize changes on the component.

Parameters:

lens - the Lens to consider for transform

delegate - transformer to use

HyperbolicShapeTransformer

protected HyperbolicShapeTransformer(Dimension d,
                                     MutableTransformer delegate)

Create an instance, setting values from the passed component and registering to listen for layoutSize changes on the component, with a possibly shared transform delegate.

Parameters:
