public interface EdgeArrowRenderingSupport<V,E>

Method Summary

AffineTransform	getArrowTransform(RenderContext<V,E> rc, Line2D edgeShape, Shape vertexShape) This is used for the arrow of a directed and for one of the arrows for non-directed edges Get a transform to place the arrow shape on the passed edge at the point where it intersects the passed shape
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.
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.
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.

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.

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.

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 staring point is not inside the vertex. The passedGo flag handles this case.

Parameters:

edgeShape -

vertexShape -

passedGo - - used only for Loop edges

getArrowTransform

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

This is used for the arrow of a directed and for one of the arrows for non-directed edges Get a transform to place the arrow shape on the passed edge at the point where it intersects the passed shape

Parameters:

edgeShape -

vertexShape -

Returns:
