17 deferred class GCurve from BRep inherits CurveRepresentation from BRep
19 ---Purpose: Root class for the geometric curves
20 -- representation. Contains a range.
29 Initialize(L : Location from TopLoc; First, Last : Real);
31 SetRange(me : mutable; First, Last : Real)
35 Range(me; First, Last : out Real)
39 First(me) returns Real
47 First(me : mutable; F : Real)
51 Last(me : mutable; L : Real)
56 D0(me; U : Real; P : out Pnt from gp)
57 ---Purpose: Computes the point at parameter U.
62 ---Purpose: Recomputes any derived data after a modification.
63 -- This is called when the range is modified.
