ShapeFix_WireSegment Class Reference

This class is auxiliary class used in ComposeShell.
It is intended for representing segment of the wire
(or whole wire). The segment itself is represented by
ShapeExtend_WireData. In addition, some associated data
necessary for computations are stored:

* Orientation flag - determines current use of the segment
and used for parity checking:

TopAbs_FORWARD and TopAbs_REVERSED - says that segment was
traversed once in the corresponding direction, and hence
it should be traversed once more in opposite direction;

TopAbs_EXTERNAL - the segment was not yet traversed in any
direction (i.e. not yet used as boundary)

TopAbs_INTERNAL - the segment was traversed in both
directions and hence is out of further work.

Segments of initial bounding wires are created with
orientation REVERSED (for outer wire) or FORWARD (for inner
wires), and segments of splitting seams - with orientation
EXTERNAL.

 ShapeFix_WireSegment ()
 Creates empty segment.

 ShapeFix_WireSegment (const Handle< ShapeExtend_WireData > &wire, const TopAbs_Orientation ori=TopAbs_EXTERNAL)
 Creates segment and initializes it with wire and orientation.

 ShapeFix_WireSegment (const TopoDS_Wire &wire, const TopAbs_Orientation ori=TopAbs_EXTERNAL)
 Creates segment and initializes it with wire and orientation.

void Clear ()
 Clears all fields.

void Load (const Handle< ShapeExtend_WireData > &wire)
 Loads wire.

const Handle_ShapeExtend_WireData & WireData () const
 Returns wire.

void Orientation (const TopAbs_Orientation ori)
 Sets orientation flag.

TopAbs_Orientation Orientation () const
 Returns orientation flag.

TopoDS_Vertex FirstVertex () const
 Returns first vertex of the first edge in the wire
(no dependance on Orientation()).

TopoDS_Vertex LastVertex () const
 Returns last vertex of the last edge in the wire
(no dependance on Orientation()).

Standard_Boolean IsClosed () const
 Returns True if FirstVertex() == LastVertex()

Standard_Integer NbEdges () const
 Returns Number of edges in the wire

TopoDS_Edge Edge (const Standard_Integer i) const
 Returns edge by given index in the wire

void SetEdge (const Standard_Integer i, const TopoDS_Edge &edge)
 Replaces edge at index i by new one.

void AddEdge (const Standard_Integer i, const TopoDS_Edge &edge)
 Insert a new edge with index i and implicitly defined
patch indices (indefinite patch).
If i==0, edge is inserted at end of wire.

void AddEdge (const Standard_Integer i, const TopoDS_Edge &edge, const Standard_Integer iumin, const Standard_Integer iumax, const Standard_Integer ivmin, const Standard_Integer ivmax)
 Insert a new edge with index i and explicitly defined
patch indices. If i==0, edge is inserted at end of wire.

void SetPatchIndex (const Standard_Integer i, const Standard_Integer iumin, const Standard_Integer iumax, const Standard_Integer ivmin, const Standard_Integer ivmax)
 Set patch indices for edge i.

void DefineIUMin (const Standard_Integer i, const Standard_Integer iumin)
void DefineIUMax (const Standard_Integer i, const Standard_Integer iumax)
void DefineIVMin (const Standard_Integer i, const Standard_Integer ivmin)
void DefineIVMax (const Standard_Integer i, const Standard_Integer ivmax)
 Modify minimal or maximal patch index for edge i.
The corresponding patch index for that edge is modified so
as to satisfy eq. iumin <= myIUMin(i) <= myIUMax(i) <= iumax

void GetPatchIndex (const Standard_Integer i, Standard_Integer &iumin, Standard_Integer &iumax, Standard_Integer &ivmin, Standard_Integer &ivmax) const
 Returns patch indices for edge i.

 Checks patch indices for edge i to satisfy equations
IUMin(i) <= IUMax(i) <= IUMin(i)+1

void SetVertex (const TopoDS_Vertex &theVertex)
TopoDS_Vertex GetVertex () const
Standard_Boolean IsVertex () const
