Description copied from interface: GenericEdgeRealizer.PathCalculator

Callback method for GenericEdgeRealizer.calculatePath(java.awt.geom.Point2D, java.awt.geom.Point2D) ()}. This method should modify the given path instance and return whether it took into account the length of the source and/or target arrow.

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:

either EdgeRealizer.PATH_UNCLIPPED, EdgeRealizer.PATH_CLIPPED_AT_SOURCE, EdgeRealizer.PATH_CLIPPED_AT_TARGET, or EdgeRealizer.PATH_CLIPPED_AT_SOURCE_AND_TARGET
