getArrowTransform
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.- Parameters:
rc
- the rendering context used for rendering the arrowedgeShape
- the shape used to draw the edgevertexShape
- 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)
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 arrowedgeShape
- the shape used to draw the edgevertexShape
- 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 arrowedgeShape
- the shape used to draw the edgevertexShape
- the shape used to draw the vertexpassedGo
- used for rendering loop edges- Returns:
- a transform used for positioning the arrowhead for this vertex and edge
