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,

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.
