Static Public Member Functions
static bool	IsClosed (const BRepGraph &theGraph, const BRepGraph_WireId theWire)
	Returns true if the wire is topologically closed.
static uint32_t	NbCoEdges (const BRepGraph &theGraph, const BRepGraph_WireId theWire)
	Number of CoEdge references in the wire (raw count: seam halves count twice, matching TopoDS_Iterator(wire) semantics).
static uint32_t	NbDistinctEdges (const BRepGraph &theGraph, const BRepGraph_WireId theWire)
	Number of distinct underlying edges in the wire (seam halves count once).
static BRepGraph_FaceId	FaceOf (const BRepGraph &theGraph, const BRepGraph_WireId theWire)
	Returns the first owning face for this wire via the reverse-index table. Returns an invalid id if the wire has no owning face (free wire).
static bool	IsOuter (const BRepGraph &theGraph, const BRepGraph_WireId theWire)
	Returns true if this wire is the outer boundary (IsOuter flag) of its owning face. Scans WireRefs that reference this wire. Returns false for free wires (no owning face).

Detailed Description

Wire property accessors.

Provides wire closure, size, and ownership queries. For ordered edge traversal, use BRepGraphInc_WireExplorer or access the WireDef::CoEdgeRefIds vector directly via TopoView.

Member Function Documentation

FaceOf()

static BRepGraph_FaceId BRepGraph_Tool::Wire::FaceOf ( const BRepGraph & theGraph, const BRepGraph_WireId theWire )

static

Returns the first owning face for this wire via the reverse-index table. Returns an invalid id if the wire has no owning face (free wire).

Parameters

[in]	theGraph	source graph
[in]	theWire	typed wire definition identifier

Returns

owning face id, or invalid

IsClosed()

static bool BRepGraph_Tool::Wire::IsClosed ( const BRepGraph & theGraph, const BRepGraph_WireId theWire )

static

Returns true if the wire is topologically closed.

Parameters

[in]	theGraph	source graph
[in]	theWire	typed wire definition identifier

Returns

true if closed

IsOuter()

static bool BRepGraph_Tool::Wire::IsOuter ( const BRepGraph & theGraph, const BRepGraph_WireId theWire )

static

Returns true if this wire is the outer boundary (IsOuter flag) of its owning face. Scans WireRefs that reference this wire. Returns false for free wires (no owning face).

Parameters

[in]	theGraph	source graph
[in]	theWire	typed wire definition identifier

Returns

true if outer wire

NbCoEdges()

static uint32_t BRepGraph_Tool::Wire::NbCoEdges ( const BRepGraph & theGraph, const BRepGraph_WireId theWire )

static

Number of CoEdge references in the wire (raw count: seam halves count twice, matching TopoDS_Iterator(wire) semantics).

Parameters

[in]	theGraph	source graph
[in]	theWire	typed wire definition identifier

Returns

number of coedge entries

NbDistinctEdges()

static uint32_t BRepGraph_Tool::Wire::NbDistinctEdges ( const BRepGraph & theGraph, const BRepGraph_WireId theWire )

static

Number of distinct underlying edges in the wire (seam halves count once).

Parameters

[in]	theGraph	source graph
[in]	theWire	typed wire definition identifier

Returns

number of distinct EdgeDefIds reachable from the wire's CoEdgeRefIds
