public class VertexShapeFactory
extends java.lang.Object
Shape
s for drawing vertices.
The available shapes include rectangles, rounded rectangles, ellipses,
regular polygons, and regular stars. The dimensions of the requested
shapes are defined by the specified VertexSizeFunction
and VertexAspectRatioFunction
implementations: the width
of the bounding box of the shape is given by the vertex size, and the
height is given by the size multiplied by the vertex's aspect ratio.Modifier and Type | Field and Description |

10 and a constant aspect ratio of 1. |
VertexShapeFactory(VertexSizeFunction vsf,
VertexAspectRatioFunction varf)
Creates a
VertexShapeFactory with the specified
vertex size and aspect ratio functions. |
