       public interface IMarkerCapable
      

Interface implemented by elements that support marker drawing. Defines methods for working with markers.

Method Summary

Modifier and Type	Method	Description
void	drawMarker(SvgDrawContext context, MarkerVertexType markerVertexType)	Draws a marker in the specified context.
double	getAutoOrientAngle(MarkerSvgNodeRenderer marker, boolean reverse)	Calculates marker orientation angle if orient attribute is set to auto

Method Details

drawMarker

             void drawMarker
             (SvgDrawContext context, MarkerVertexType markerVertexType)
            

Draws a marker in the specified context. The marker is drawn on the vertices defined according to the given marker type.

Parameters:

context - the object that knows the place to draw this element and maintains its state

markerVertexType - type of marker that determine on which vertices of the given element marker should be drawn

getAutoOrientAngle

             double getAutoOrientAngle
             (MarkerSvgNodeRenderer marker, boolean reverse)
            

Calculates marker orientation angle if orient attribute is set to auto

Parameters:

marker - marker for which the rotation angle should be calculated

reverse - indicates that the resulting angle should be rotated 180 degrees

Returns:

marker orientation angle so that its positive x-axis is pointing in the direction of the path at the point it is placed
