Method Detail

paintEdge

public void paintEdge(RenderContext<V,E> rc,
                      Layout<V,E> layout,
                      E e)

Specified by:

paintEdge in interface Renderer.Edge<V,E>

prepareFinalEdgeShape

protected Shape prepareFinalEdgeShape(RenderContext<V,E> rc,
                                      Layout<V,E> layout,
                                      E e,
                                      int[] coords,
                                      boolean[] loop)

drawSimpleEdge

protected void drawSimpleEdge(RenderContext<V,E> rc,
                              Layout<V,E> layout,
                              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).

Parameters:

rc - the render context used for rendering the edge

layout - the layout instance which provides the edge's endpoints' coordinates

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>
