Detailed Description

Non-const view for programmatic graph construction and structural editing.

The single mutation entry point for a BRepGraph instance. Provides:

• Structural creation via entity-scoped nested Ops classes (VertexOps, EdgeOps, CoEdgeOps, WireOps, FaceOps, ShellOps, SolidOps, CompoundOps, CompSolidOps, ProductOps, GenOps) to create topology definition nodes (vertices, edges, wires, faces, shells, solids, compounds) and assembly nodes (products, occurrences) without an existing TopoDS_Shape.
• Field-level RAII-scoped mutation via Mut*() guards (Edges().Mut, Faces().Mut, Products().Mut, Occurrences().Mut, Edges().Mut, Faces().Mut, etc.) with automatic cache invalidation and upward SubtreeGen propagation on guard destruction.
• Incremental shape appending, soft-deletion of nodes, and deferred invalidation mode for batched structural edit loops under external serialization. Obtained via BRepGraph::Editor().

Each Ops class is accessed via a non-const reference accessor: theGraph.Editor().Vertices().Add(...) theGraph.Editor().Edges().Add(...) theGraph.Editor().CoEdges().Add(edge, face, curve2d, first, last, ori) theGraph.Editor().Products().Add(shapeRoot, placement) theGraph.Editor().Gen().RemoveNode(...)

Contract notes:

• Add* methods return BRepGraph_NodeId() on invalid inputs and do not partially modify the graph; call IsValid() on the returned id to check success
• invalid inputs include wrong kind, out-of-range ids, or removed referenced nodes unless a method documents stricter accepted-input rules
• linking methods such as Shells().Add() and Solids().Add() return an invalid typed RefId on failure and otherwise keep ownership explicit in the reference layer
• use Mut*() guards for scoped field mutation on existing active definitions, references, and representations

Member Function Documentation

BeginDeferredInvalidation()

void BRepGraph::EditorView::BeginDeferredInvalidation

(

)

Begin deferred invalidation mode. While active, markModified() only increments OwnGen + SubtreeGen and appends to the deferred list - without acquiring the shape-cache mutex or propagating upward. Call EndDeferredInvalidation() to batch-flush all accumulated changes. Intended for batch mutation loops (SameParameter, Sewing) where many entities are modified sequentially and upward propagation should be deferred until all mutations are complete. Prefer BRepGraph_DeferredScope RAII guard.

Warning

Deferred mode batches invalidation only; it does NOT serialize the mutation body. Callers must guarantee exclusive Editor() structural edit access for the whole deferred scope; concurrent Editor().Mut*() usage still requires external synchronization around the surrounding batch.

CoEdges()

CoEdgeOps & BRepGraph::EditorView::CoEdges ( )

inline

Return coedge and PCurve operations.

CommitMutation()

void BRepGraph::EditorView::CommitMutation ( )

noexcept

Finalize a batch of mutations. Validates relation consistency and asserts active entity counts match actual entity state. Call this after manual batch mutation loops, or rely on BRepGraph_DeferredScope to call it automatically at scope exit.

Compounds()

CompoundOps & BRepGraph::EditorView::Compounds ( )

inline

Return compound creation and editing operations.

CompSolids()

CompSolidOps & BRepGraph::EditorView::CompSolids ( )

inline

Return compsolid creation and editing operations.

Edges()

EdgeOps & BRepGraph::EditorView::Edges ( )

inline

Return edge creation and editing operations.

EndDeferredInvalidation()

void BRepGraph::EditorView::EndDeferredInvalidation ( )

noexcept

End deferred invalidation mode and batch-flush: propagates SubtreeGen upward for all modified entities from the deferred list. Shape cache entries are validated lazily via SubtreeGen comparison.

Faces()

FaceOps & BRepGraph::EditorView::Faces ( )

inline

Return face creation and editing operations.

Gen()

GenOps & BRepGraph::EditorView::Gen ( )

inline

Return generic node, reference, and representation removal operations.

IsDeferredMode()

bool BRepGraph::EditorView::IsDeferredMode

(

)

const

Check if deferred invalidation mode is currently active.

Note

This is a state flag only. It does not imply mutation ownership or synchronization guarantees.

Occurrences()

OccurrenceOps & BRepGraph::EditorView::Occurrences ( )

inline

Return occurrence mutation operations.

Products()

ProductOps & BRepGraph::EditorView::Products ( )

inline

Return product and assembly creation and editing operations.

Shells()

ShellOps & BRepGraph::EditorView::Shells ( )

inline

Return shell creation and editing operations.

Solids()

SolidOps & BRepGraph::EditorView::Solids ( )

inline

Return solid creation and editing operations.

Supplement()

BRepGraph_SupplementEditor BRepGraph::EditorView::Supplement ( )

inline

Return runtime supplement attachment operations.

ValidateMutationBoundary()

bool BRepGraph::EditorView::ValidateMutationBoundary

(

NCollection_LinearVector< BoundaryIssue > *const

theIssues = nullptr

)

const

Validate lightweight mutation-boundary invariants.

Parameters

[out]

theIssues

optional destination for detailed issues

Returns

true if no issues were found

Vertices()

VertexOps & BRepGraph::EditorView::Vertices ( )

inline

Return vertex creation operations.

Wires()

WireOps & BRepGraph::EditorView::Wires ( )

inline

Return wire creation and editing operations.
