getArrowTransform

public java.awt.geom.AffineTransform getArrowTransform(RenderContext<V,E> rc,
                                                       java.awt.Shape edgeShape,
                                                       java.awt.Shape vertexShape)

Description copied from interface: EdgeArrowRenderingSupport

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 interface EdgeArrowRenderingSupport<V,E>

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

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

Description copied from interface: EdgeArrowRenderingSupport

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 interface EdgeArrowRenderingSupport<V,E>

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

public java.awt.geom.AffineTransform getReverseArrowTransform(RenderContext<V,E> rc,
                                                              java.awt.Shape edgeShape,
                                                              java.awt.Shape vertexShape,
                                                              boolean passedGo)

Description copied from interface: EdgeArrowRenderingSupport

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.

Specified by:

getReverseArrowTransform in interface EdgeArrowRenderingSupport<V,E>

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

public java.awt.geom.AffineTransform getArrowTransform(RenderContext<V,E> rc,
                                                       java.awt.geom.Line2D edgeShape,
                                                       java.awt.Shape vertexShape)

Description copied from interface: EdgeArrowRenderingSupport

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 interface EdgeArrowRenderingSupport<V,E>

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
