dispatchToGeometryHandler MethodAbstract

  • "double dispatch" call pattern.
  • User code implements a GeometryHandler with specialized methods to handle LineSegment3d, Arc3d etc as relevant to its use case.
  • Each such GeometryQuery class implements this method as a one-line method containing the appropriate call such as handler.handleLineSegment3d ()
  • This allows each type-specific method to be called without a switch or instanceof test.
