Method Detail

paintEdge

public void paintEdge(RenderContext<V,E> renderContext,
                      LayoutModel<V> layoutModel,
                      E e)

Specified by:

paintEdge in interface Renderer.Edge<V,E>

prepareFinalEdgeShape

protected Shape prepareFinalEdgeShape(RenderContext<V,E> renderContext,
                                      LayoutModel<V> layoutModel,
                                      E e,
                                      int[] coords,
                                      boolean[] loop)

getEdgeShape

protected abstract Shape getEdgeShape(BiFunction<org.jgrapht.Graph<V,E>,E,Shape> edgeShapeFunction,
                                      E edge,
                                      org.jgrapht.Graph<V,E> graph)

For Heavyweight graph visualizations, edges are rendered with the user requested edgeShapeFunction. For Lightweight graph visualizations, edges are rendered with a (lightweight) line edge except when they are articulated edges (sugiyama layout). The LightweightEdgeRenderer overrides this method to supply the correct edge shape.

Parameters:

edgeShapeFunction - the user specified edgeShapeFunction

edge - the edge to render

graph - for the Function context

Returns:

the edge shape, heavyweight (anything) or lightweight (line or articulated line)

drawSimpleEdge

protected abstract void drawSimpleEdge(RenderContext<V,E> renderContext,
                                       LayoutModel<V> layoutModel,
                                       E e)
