Method Detail

getArrowTransform

AffineTransform getArrowTransform(RenderContext<V,E> rc,
                                  Shape edgeShape,
                                  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

AffineTransform getReverseArrowTransform(RenderContext<V,E> rc,
                                         Shape edgeShape,
                                         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

AffineTransform getReverseArrowTransform(RenderContext<V,E> rc,
                                         Shape edgeShape,
                                         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

getArrowTransform

AffineTransform getArrowTransform(RenderContext<V,E> rc,
                                  Line2D edgeShape,
                                  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
