deferred class Curve from Bisector 

	---Purpose: 

inherits
    Curve from Geom2d

uses
    Pnt2d from gp

is
    
    Parameter ( me ; P : Pnt2d from gp) returns Real
    is deferred;
    
    IsExtendAtStart (me) returns Boolean from Standard
    is deferred;
    
    IsExtendAtEnd   (me) returns Boolean from Standard
    is deferred;

    NbIntervals (me) returns Integer
	---Purpose: If necessary,  breaks the  curve in  intervals  of
	--          continuity  <C1>.    And  returns   the number   of
	--          intervals.
    is deferred;

    IntervalFirst(me; Index : Integer from Standard) returns Real
       ---Purpose: Returns  the  first  parameter    of  the  current
       --          interval. 
    is deferred;
    
    IntervalLast(me; Index : Integer from Standard) returns Real
       ---Purpose: Returns  the  last  parameter    of  the  current
       --          interval. 
    is deferred;
    
end Curve;
