class Pnt2dBisec

from GccAna

	---Purpose: This class implements the algorithms used to 
	--          create the bisecting line between two 2d points 
    	-- Describes functions for building a bisecting line between two 2D points.
    	-- The bisecting line between two points is the bisector of
    	-- the segment which joins the two points, if these are not coincident.
    	-- The algorithm does not find a solution if the two points are coincident.
    	-- A Pnt2dBisec object provides a framework for:
    	-- -   defining the construction of the bisecting line,
    	-- -   implementing the construction algorithm, and consulting the result.

uses Pnt2d           from gp,

raises NotDone       from StdFail

is

Create(Point1    : Pnt2d from gp ;
       Point2    : Pnt2d from gp ) returns Pnt2dBisec;

    	---Purpose: Constructs a bisecting line between the points Point1 and Point2.

IsDone(me) returns Boolean from Standard
is static;
    	---Purpose: Returns true (this construction algorithm never fails).
        
HasSolution(me) returns Boolean from Standard
is static;
    	---Purpose: Returns true if this algorithm has a solution, i.e. if the
    	-- two points are not coincident.
        
ThisSolution(me) returns Lin2d from gp
raises NotDone
is static;
    	---Purpose : Returns a line, representing the solution computed by this algorithm.
