deferred class Point from Geom2d inherits Geometry from Geom2d

        --- Purpose : The abstract class Point describes the common
    	-- behavior of geometric points in 2D space.
    	-- The Geom2d package also provides the concrete
    	-- class Geom2d_CartesianPoint.

uses Pnt2d from gp

  Coord (me; X, Y : out Real) 
        --- Purpose : returns the Coordinates of <me>.
     is deferred;


  Pnt2d (me)  returns Pnt2d
        --- Purpose : returns a non persistent copy of <me>
     is deferred;


  X (me)  returns Real
        --- Purpose : returns the X coordinate of <me>.
     is deferred;


  Y (me)  returns Real
        --- Purpose : returns  the Y coordinate of <me>.
     is deferred;



  Distance (me; Other : Point)  returns Real;
        --- Purpose : computes the distance between <me> and <Other>.

  
  SquareDistance (me; Other : Point)  returns Real;
        --- Purpose : computes the square distance between <me> and <Other>.
