Method Detail

getEdgeShape

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

For the LightweightEdgeRenderer, we only want the default 'line' edge shape when the edge is not an articulated edge

Specified by:

getEdgeShape in class AbstractEdgeRenderer<V,E>

Parameters:

edgeShapeFunction - the visualization's edge shape function

edge - the edge to render

graph - the graph (for the function context)

Returns:

either a (lightweight) line edge or an articulated edge

drawSimpleEdge

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

Draws the edge e, whose endpoints are at (x1,y1) and (x2,y2) , on the graphics context g. The Shape provided by the EdgeShapeFunction instance is scaled in the x-direction so that its width is equal to the distance between (x1,y1) and (x2,y2).

Specified by:

drawSimpleEdge in class AbstractEdgeRenderer<V,E>

Parameters:

e - the edge to be drawn

getEdgeArrowRenderingSupport

public EdgeArrowRenderingSupport<V,E> getEdgeArrowRenderingSupport()

Specified by:

getEdgeArrowRenderingSupport in interface Renderer.Edge<V,E>

setEdgeArrowRenderingSupport

public void setEdgeArrowRenderingSupport(EdgeArrowRenderingSupport<V,E> edgeArrowRenderingSupport)

Specified by:

setEdgeArrowRenderingSupport in interface Renderer.Edge<V,E>
