Class PolyLinePathCalculator

java.lang.Object
  y.view.PolyLinePathCalculator

All Implemented Interfaces:

GenericEdgeRealizer.PathCalculator

public class PolyLinePathCalculator
extends java.lang.Object
implements GenericEdgeRealizer.PathCalculator

Calculates the visible path of an edge as a polyline. The behavior of this path calculator is similar to the path calculated for class PolyLineEdgeRealizer.

Constructor Summary

Method Detail

calculatePath

public byte calculatePath(EdgeRealizer context,
                          BendList bends,
                          java.awt.geom.GeneralPath path,
                          java.awt.geom.Point2D sourceIntersectionPointOut,
                          java.awt.geom.Point2D targetIntersectionPointOut)

Calculates the visible path of an edge as a polyline. The given realizer's bends are the control points for the polyline.

Specified by:

calculatePath in interface GenericEdgeRealizer.PathCalculator

Parameters:

context - the context EdgeRealizer

bends - the current BendList

path - the current GeneralPath

sourceIntersectionPointOut - the point to place the source intersection point in

targetIntersectionPointOut - the point to place the target intersection point in

Returns:

one of EdgeRealizer.PATH_UNCLIPPED, EdgeRealizer.PATH_CLIPPED_AT_SOURCE, EdgeRealizer.PATH_CLIPPED_AT_TARGET, or EdgeRealizer.PATH_CLIPPED_AT_SOURCE_AND_TARGET.
