class AlgoContainer from ShapeAlgo inherits TShared from MMgt
---Purpose:
uses
Curve from Geom2d,
BSplineCurve from Geom2d,
BSplineCurve from Geom,
BSplineSurface from Geom,
Surface from Geom,
SequenceOfCurve from TColGeom,
HSequenceOfBoundedCurve from TColGeom,
SequenceOfCurve from TColGeom2d,
HSequenceOfBoundedCurve from TColGeom2d,
Shape from TopoDS,
Edge from TopoDS,
Wire from TopoDS,

Curve from Geom,
Shape from GeomAbs
is
Create returns mutable AlgoContainer from ShapeAlgo;
---Purpose: Empty constructor
SetToolContainer (me: mutable; TC: ToolContainer from ShapeAlgo);
---C++ : inline
---Purpose: Sets ToolContainer
ToolContainer (me) returns ToolContainer from ShapeAlgo;
---C++ : inline
---Purpose: Returns ToolContainer
--- Algorithms
ConnectNextWire (me; saw : Wire from ShapeAnalysis;
nextsewd : WireData from ShapeExtend;
maxtol : Real;
distmin : out Real;
revsewd : out Boolean;
revnextsewd: out Boolean)
returns Boolean is virtual;
---Purpose: Finds the best way to connect and connects <nextsewd> to already
-- built <sewd> (in <saw>).
-- Returns False if <nextsewd> cannot be connected, otherwise - True.
-- <maxtol> specifies the maximum tolerance with which <nextsewd> can
-- be added.
-- <distmin> is used to receive the minimum distance between <nextsewd>
-- and <sewd>.
-- <revsewd> is True if <sewd> has been reversed before connecting.
-- <revnextwd> is True if <nextsewd> has been reversed before connecting.
-- Uses functionality of ShapeAnalysis_Wire.
ApproxBSplineCurve (me; bspline: BSplineCurve from Geom; seq: out SequenceOfCurve from TColGeom)
is virtual;
---Purpose:
ApproxBSplineCurve (me; bspline: BSplineCurve from Geom2d; seq: out SequenceOfCurve from TColGeom2d)
is virtual;
---Purpose:

returns Boolean is virtual;
C0BSplineToSequenceOfC1BSplineCurve (me; BS : BSplineCurve from Geom2d;
seqBS: out HSequenceOfBoundedCurve from TColGeom2d)
returns Boolean is virtual;
---Purpose: Converts C0 B-Spline curve into sequence of C1 B-Spline curves.
-- Calls ShapeUpgrade::C0BSplineToSequenceOfC1BSplineCurve.
C0ShapeToC1Shape (me; shape: Shape from TopoDS; tol: Real)
returns Shape from TopoDS is virtual;
---Purpose: Converts a shape on C0 geometry into the shape on C1 geometry.
---Remark : Uses ShapeUpgrade_ShapeDivide.
ConvertSurfaceToBSpline(me; surf : Surface from Geom;
UF,UL,VF,VL: Real)
returns BSplineSurface from Geom is virtual;
---Purpose: Converts a surface to B-Spline.
-- Uses ShapeConstruct.

wireIn2 : Wire from TopoDS;
wireOut1: out Wire from TopoDS;
wireOut2: out Wire from TopoDS;
byParam : Boolean from Standard)
returns Boolean is virtual;
---Purpose: Return 2 wires with the same number of edges. The both Edges
-- number i of these wires have got the same ratio between
-- theirs parameter lengths and their wire parameter lengths.
OuterWire (me; face: Face from TopoDS) returns Wire from TopoDS is virtual;
---Purpose: Returns the outer wire on the face <Face>.
ConvertToPeriodic (me; surf: Surface from Geom)
returns Surface from Geom is virtual;
---Purpose: Converts surface to periodic form.
-- Calls ShapeCustom_Surface.
GetFaceUVBounds (me; F: Face from TopoDS; Umin, Umax, Vmin, Vmax: out Real)
is virtual;
---Purpose: Computes exact UV bounds of all wires on the face
---Remark : Calls ShapeAnalysis::GetFaceUVBounds.

First : Real;
Last : Real;
Tol3d : Real;
Continuity : Shape from GeomAbs;
MaxSegments: Integer;
MaxDegree : Integer)
returns BSplineCurve from Geom is virtual;
---Purpose: Convert Geom_Curve to Geom_BSplineCurve
---Remark : Calls ShapeConstruct::CurveCurveToBSplineCurve.
