getArrowTransform
public java.awt.geom.AffineTransform getArrowTransform(RenderContext<V,E> rc, java.awt.Shape edgeShape, 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.- Specified by:
getArrowTransform
in interfaceEdgeArrowRenderingSupport<V,E>
-
getReverseArrowTransform
public java.awt.geom.AffineTransform getReverseArrowTransform(RenderContext<V,E> rc, java.awt.Shape edgeShape, 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.- Specified by:
getReverseArrowTransform
in interfaceEdgeArrowRenderingSupport<V,E>
-
getReverseArrowTransform
public 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 staring point is not inside the vertex. The passedGo flag handles this case.
- Specified by:
getReverseArrowTransform
in interfaceEdgeArrowRenderingSupport<V,E>
- Parameters:
path
-vertexShape
-passedGo
- - used only for Loop edges
