paintShape

public void paintShape(mxGraphics2DCanvas canvas,
              mxCellState state)

Specified by:

paintShape in interface mxIShape

Overrides:

paintShape in class mxConnectorShape

paintPolyline

protected void paintPolyline(mxGraphics2DCanvas canvas,
                 List<mxPoint> points,
                 Map<String,Object> style)

Overrides:

paintPolyline in class mxConnectorShape

validateCurve

public void validateCurve(List<mxPoint> points,
                 double scale,
                 Map<String,Object> style)

Forces underlying curve to a valid state

Parameters:

points -

getMarkerVector

protected mxLine getMarkerVector(List<mxPoint> points,
                     boolean source,
                     double markerSize)

Hook to override creation of the vector that the marker is drawn along since it may not be the same as the vector between any two control points

Overrides:

getMarkerVector in class mxConnectorShape

Parameters:

points - the guide points of the connector

source - whether the marker is at the source end

markerSize - the scaled maximum length of the marker

Returns:

a line describing the vector the marker should be drawn along
