Detailed Description

Wire property accessors.

Provides wire closure, size, and ownership queries. For ordered coedge traversal, use BRepGraph_CoEdgesOfWire or TopoView::Wires().Relations(theWire).CoEdgeIds.

Member Function Documentation

FaceOf() [1/2]

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

static

Returns the first owning face for this wire via relation tables. 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

FaceOf() [2/2]

static BRepGraph_FaceId BRepGraph_Tool::Wire::FaceOf ( const BRepGraph & theGraph, const BRepGraph_WireRefId theWireRef )

static

Returns the first owning face for the referenced wire.

IsClosed() [1/2]

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

static

Returns true if the wire is topologically closed, derived from ordered coedge chain.

Parameters

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

Returns

true if closed

IsClosed() [2/2]

static bool BRepGraph_Tool::Wire::IsClosed ( const BRepGraph & theGraph, const BRepGraph_WireRefId theWireRef )

static

Returns true if the referenced wire is topologically closed.

IsOuter() [1/2]

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

static

Returns true if this wire is the first active wire 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

IsOuter() [2/2]

static bool BRepGraph_Tool::Wire::IsOuter ( const BRepGraph & theGraph, const BRepGraph_WireRefId theWireRef )

static

Returns true if the referenced wire is the outer wire of its owning face.

NbCoEdges() [1/2]

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

static

Number of CoEdge usages 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

NbCoEdges() [2/2]

static uint32_t BRepGraph_Tool::Wire::NbCoEdges ( const BRepGraph & theGraph, const BRepGraph_WireRefId theWireRef )

static

Number of CoEdge usages in the referenced wire.

NbDistinctEdges() [1/2]

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 ChildEdgeIds reachable from the wire's CoEdgeIds

NbDistinctEdges() [2/2]

static uint32_t BRepGraph_Tool::Wire::NbDistinctEdges ( const BRepGraph & theGraph, const BRepGraph_WireRefId theWireRef )

static

Number of distinct underlying edges in the referenced wire.

Usage()

Resolves a wire reference id to a lightweight usage value.

Parameters

[in]	theGraph	source graph
