BRepGraphInc_BaseRef

Constructors(1)

constructor(): BRepGraphInc_BaseRef

Properties(1)

UID:number

Contiguous bit-vector for per-entity boolean flags.
Stores one bit per entity index in a flat array of 64-bit blocks. Provides O(1) Set/Clear/Test operations and cache-friendly sequential traversal (512 flags per 64-byte cache line via eight 64-bit blocks).
Used by BRepGraphInc_Storage to store IsRemoved and IsOwned flags outside the entity structs, improving cache locality during traversal and reducing struct size by eliminating bool-field padding.
Public helpers in BRepGraphInc_Storage validate indices before reaching this low-level container. Set, Clear, and Test remain unchecked for hot internal paths that already proved the index is in range.

BRepGraphInc_Populate

Backend topology/geometry population for BRepGraph.
This class is part of the BRepGraphInc backend and is intended for backend maintenance, tests, and low-level infrastructure only. External code should enter through BRepGraph::ShapesView::Add(), which owns the public lifecycle, cache invalidation, and layer coordination.
The builder stores forward child relations only. Reverse relations are rebuilt by BRepGraphInc_Storage after population.

Static methods(3)

Perform(theGraph: BRepGraph, theShape: TopoDS_Shape, theParallel: boolean, theOptions?: BRepGraphInc_Populate_Options): BRepGraphInc_Populate_BuildStatus
Build backend incidence storage from a TopoDS_Shape.
Parameters (4)
- theGraph —
  graph whose storage to populate (cleared first)
- theShape —
  root shape
- theParallel —
  if true, face-level extraction runs in parallel
- theOptions —
  optional post-pass controls
Returns
build status indicating success, warnings, or failure
AppendFlattened(theGraph: BRepGraph, theShape: TopoDS_Shape, theParallel: boolean, theAppendedRoots: BRepGraph_NodeId[], theOptions: BRepGraphInc_Populate_Options): BRepGraphInc_Populate_BuildStatus
Extend existing backend storage with additional shapes (no clear). Flattens hierarchy containers away; Solid/Shell/Compound/CompSolid inputs contribute appended face roots instead of container entities. Recomputes the built-in metadata layers from the populated storage.
Parameters (5)
- theGraph —
  graph whose storage to extend
- theShape —
  shape to append
- theParallel —
  if true, face-level extraction runs in parallel
- theAppendedRoots —
  collected root NodeIds for non-container shapes Mutated in place; read the updated value from this argument after the call.
- theOptions —
  optional post-pass controls
Returns
build status indicating success, warnings, or failure
Append(theGraph: BRepGraph, theShape: TopoDS_Shape, theParallel: boolean, theOptions?: BRepGraphInc_Populate_Options): BRepGraphInc_Populate_BuildStatus
Extend existing backend storage with additional shapes (no clear). Preserves the full shape hierarchy: Solid/Shell/Compound/CompSolid nodes are created alongside Face/Edge/Vertex nodes. Shapes already present in the storage with the same definition identity (TShape + Location, orientation ignored) are deduplicated and not re-added.
Parameters (4)
- theGraph —
  graph whose storage to extend
- theShape —
  shape to append
- theParallel —
  if true, face-level extraction runs in parallel
- theOptions —
  optional post-pass controls
Returns
build status indicating success, warnings, or failure

BRepGraphInc_Reconstruct

Backend reconstruction helpers over incidence-table storage.
Converts BRepGraphInc_Storage entity data back into TopoDS shapes. This class is part of the BRepGraphInc backend; external callers should prefer BRepGraph::Shapes() so reconstruction stays behind the facade. Supports single-node and cached multi-face reconstruction with shared edge/vertex reuse via the Cache.

Static methods(3)

Node(theGraph: BRepGraph, theNode: BRepGraph_NodeId): TopoDS_Shape
Reconstruct a TopoDS_Shape from an entity node. Creates a local cache internally; shared vertices/edges are not reused across calls.
Parameters (2)
- theGraph —
  graph owning the storage and caches
- theNode —
  entity node id
Returns
reconstructed shape
Node(theGraph: BRepGraph, theNode: BRepGraph_NodeId, theCache: BRepGraphInc_Reconstruct_Cache): TopoDS_Shape
Reconstruct a TopoDS_Shape with a shared cache for sub-shape reuse. Vertices and edges already in theCache are returned directly.
Parameters (3)
- theGraph —
  graph owning the storage and caches
- theNode —
  entity node id
- theCache —
  shared cache for vertex/edge/face shapes Mutated in place; read the updated value from this argument after the call.
Returns
reconstructed shape
FaceWithCache(theGraph: BRepGraph, theFaceId: BRepGraph_FaceId, theCache: BRepGraphInc_Reconstruct_Cache): TopoDS_Shape
Reconstruct a face with shared edge/vertex cache for multi-face contexts.
Parameters (3)
- theGraph —
  graph owning the storage and caches
- theFaceId —
  face entity id
- theCache —
  shared cache for edge and vertex shapes Mutated in place; read the updated value from this argument after the call.
Returns
reconstructed face shape

BRepGraphInc_Storage

Central backend storage container for the incidence-table topology model.
Holds all entity vectors (Vertex through Occurrence), representation vectors (Surface, Curve3D, Curve2D, Triangulation, Polygon), relation tables for connectivity navigation, TShape deduplication maps, original shape bindings, and per-kind UID vectors. Provides typed accessors enforcing compile-time safety for backend code. External callers should normally use the BRepGraph facade rather than reaching into this storage directly. BRepGraphInc_Populate has friend access for efficient bulk writes during graph population.

Properties(1)

Index:number

BRepGraph_RepId

Lightweight typed index into a per-kind use-record vector inside BRepGraph.
The pair (Kind, Index) forms a unique use-record identifier within one graph instance. Default-constructed RepId has Index = UINT32_MAX (invalid).
Use records are session-local representation slots with no public stable UID, graph-level lock state, independent mutation generation, or layer callbacks. They do have a soft-removed state so an owner can clear and later reuse its slot.

Constructors(2)

constructor(): BRepGraph_RepId
Default: invalid RepId.
constructor(theKind: BRepGraph_RepId_Kind, theIdx: number): BRepGraph_RepId
Parameters (2)
- theKind
- theIdx

Static methods(1)

IsValidKind(theKind: BRepGraph_RepId_Kind): boolean
True if the kind value is one of the supported use-record kinds.
Parameters (1)
- theKind

Instance methods(3)

IsValid(): boolean
True if this id points to an allocated slot.
IsValid(theMaxCount: number): boolean
True if this id is within [0, theMaxCount).
Parameters (1)
- theMaxCount
IsRemoved(theGraph: BRepGraph): boolean
Return true if this use entry has been soft-removed in the given graph.
Parameters (1)
- theGraph
