class ComparatorOfVertexOfDelaun from BRepMesh

  ---Purpose: Sort two point in a given direction.


  uses  Boolean from Standard,
        Vertex from BRepMesh,
        XY from gp


  is      Create (theDir : XY from gp; TheTol: Real from Standard) 
            returns ComparatorOfVertexOfDelaun;


          IsLower (me; Left, Right: Vertex from BRepMesh)
          ---Purpose: returns True if <Left> is lower than <Right>
          returns Boolean from Standard;

          IsGreater (me; Left, Right: Vertex from BRepMesh)
          ---Purpose: returns True if <Left> is greater than <Right>
          returns Boolean from Standard;

          IsEqual(me; Left, Right: Vertex from BRepMesh)
          ---Purpose: returns True when <Right> and <Left> are equal.
          returns Boolean from Standard;


fields  DirectionOfSort : XY from gp;
        Tolerance       : Real from Standard;
