                                                        java.awt.Shape vertexShape)
        Returns a transform to position the arrowhead on this edge shape at the point where it intersects the passed vertex shape.
        Parameters:
        rc - the rendering context used for rendering the arrow
        edgeShape - the shape used to draw the edge
        vertexShape - the shape used to draw the vertex
        Returns:
        a transform used for positioning the arrowhead for this vertex and edge
      • getReverseArrowTransform

        java.awt.geom.AffineTransform getReverseArrowTransform​(RenderContext<V,​E> rc,
                                                               java.awt.Shape edgeShape,

        Returns a transform to position the arrowhead on this edge shape at the point where it intersects the passed vertex shape.
        Parameters:
        rc - the rendering context used for rendering the arrow
        edgeShape - the shape used to draw the edge
        vertexShape - the shape used to draw the vertex
        Returns:
        a transform used for positioning the arrowhead for this vertex and edge
      • getReverseArrowTransform

        java.awt.geom.AffineTransform getReverseArrowTransform​(RenderContext<V,​E> rc,
                                                               java.awt.Shape edgeShape,
                                                               java.awt.Shape vertexShape,
                                                               boolean passedGo)
        Returns a transform to position the arrowhead on this edge shape at the point where it intersects the passed vertex shape.

        The Loop edge is a special case because its starting point is not inside the vertex. The passedGo flag handles this case.

        Parameters:
        rc - the rendering context used for rendering the arrow
        edgeShape - the shape used to draw the edge
        vertexShape - the shape used to draw the vertex
        passedGo - used for rendering loop edges
        Returns:
        a transform used for positioning the arrowhead for this vertex and edge

                                                        java.awt.Shape vertexShape)
        Returns a transform to position the arrowhead on this edge shape at the point where it intersects the passed vertex shape.
        Parameters:
        rc - the rendering context used for rendering the arrow
        edgeShape - the shape used to draw the edge
        vertexShape - the shape used to draw the vertex
        Returns:
        a transform used for positioning the arrowhead for this vertex and edge
