Data Fields
occ::handle< NCollection_BaseAllocator >	myAllocator
BRepGraphInc_Storage	myIncStorage
	Incidence-table storage - sole source of truth for all topology data, original shapes, TShape->NodeId mapping, and UIDs.
std::atomic< size_t >	myNextUIDCounter
	UID system.
std::atomic< uint32_t >	myGeneration {0}
Standard_GUID	myGraphGUID
	Random graph identity, generated at BRepGraph_Builder::Add().
BRepGraph_History	myHistoryLog
	History subsystem.
bool	myIsDone = false
NCollection_DynamicArray< BRepGraph_ProductId >	myRootProductIds
	Root product identifiers: products not referenced by any active occurrence. Maintained incrementally by Editor/EditorView mutations.
std::atomic< bool >	myDeferredMode {false}
	When true, markModified() only increments OwnGen + SubtreeGen and appends to myDeferredModified - no mutex acquisition and no upward propagation.
std::atomic< uint32_t >	myPropagationWave {0}
	Propagation wave counter. Incremented at the start of each markModified() / markRefModified() call. markParentModified() compares entity.LastPropWave against this to skip already-visited parents in the same propagation wave (O(1) re-visit guard).
uint32_t	myRemoveSubgraphDepth = 0
	Recursion depth of EditorView::GenOps::RemoveSubgraph. Outermost call (depth==0) triggers a single reverse-index rebuild after cascade so individual cascade-prune steps avoid maintaining per-kind unbinds for every removed node.
NCollection_DynamicArray< BRepGraph_NodeId >	myDeferredModified
	NodeIds accumulated during deferred mode. Processed by EndDeferredInvalidation().
NCollection_DynamicArray< BRepGraph_RefId >	myDeferredRefModified
	RefIds accumulated during deferred mode. Processed by EndDeferredInvalidation().
NCollection_DataMap< BRepGraph_NodeId, CachedShape >	myCurrentShapes
	Thread-safe cache of reconstructed shapes with SubtreeGen validation.
std::shared_mutex	myCurrentShapesMutex
NCollection_DataMap< BRepGraph_UID, BRepGraph_NodeId >	myUIDToNodeId
	Lazy reverse lookup index for entity UIDs.
std::shared_mutex	myUIDToNodeIdMutex
uint32_t	myUIDToNodeIdGeneration = 0
bool	myUIDToNodeIdDirty = true
NCollection_DataMap< BRepGraph_RefUID, BRepGraph_RefId >	myRefUIDToRefId
	Lazy reverse lookup index for reference UIDs.
std::shared_mutex	myRefUIDToRefIdMutex
uint32_t	myRefUIDToRefIdGeneration = 0
bool	myRefUIDToRefIdDirty = true
BRepGraph_MeshCacheStorage	myMeshCache
	Cached mesh data storage (algorithm-derived, non-mutating). Holds triangulation/polygon rep references written by BRepGraphMesh. Does NOT trigger markModified() or mutation tracking.
BRepGraph::TopoView	myTopoView {nullptr}
	Cached view objects (pointers set to owning BRepGraph in its constructor).
BRepGraph::UIDsView	myUIDsView {nullptr}
BRepGraph::CacheView	myCacheView {nullptr}

Detailed Description

Internal storage for BRepGraph (PIMPL).

All topology definition data and UIDs live in myIncStorage. Access via myIncStorage.Edges, myIncStorage.Faces, etc.

Field Documentation

myAllocator

occ::handle<NCollection_BaseAllocator> BRepGraph_Data::myAllocator

myCacheView

BRepGraph::CacheView BRepGraph_Data::myCacheView {nullptr}

myCurrentShapes

NCollection_DataMap<BRepGraph_NodeId, CachedShape> BRepGraph_Data::myCurrentShapes

mutable

Thread-safe cache of reconstructed shapes with SubtreeGen validation.

myCurrentShapesMutex

std::shared_mutex BRepGraph_Data::myCurrentShapesMutex

mutable

myDeferredMode

std::atomic<bool> BRepGraph_Data::myDeferredMode {false}

When true, markModified() only increments OwnGen + SubtreeGen and appends to myDeferredModified - no mutex acquisition and no upward propagation.

myDeferredModified

NCollection_DynamicArray<BRepGraph_NodeId> BRepGraph_Data::myDeferredModified

NodeIds accumulated during deferred mode. Processed by EndDeferredInvalidation().

myDeferredRefModified

NCollection_DynamicArray<BRepGraph_RefId> BRepGraph_Data::myDeferredRefModified

RefIds accumulated during deferred mode. Processed by EndDeferredInvalidation().

myEditorView

BRepGraph::EditorView BRepGraph_Data::myEditorView {nullptr}

myGeneration

std::atomic<uint32_t> BRepGraph_Data::myGeneration {0}

myGraphGUID

Standard_GUID BRepGraph_Data::myGraphGUID

Random graph identity, generated at BRepGraph_Builder::Add().

myHistoryLog

BRepGraph_History BRepGraph_Data::myHistoryLog

History subsystem.

myIncStorage

BRepGraphInc_Storage BRepGraph_Data::myIncStorage

Incidence-table storage - sole source of truth for all topology data, original shapes, TShape->NodeId mapping, and UIDs.

myIsDone

bool BRepGraph_Data::myIsDone = false

myMeshCache

BRepGraph_MeshCacheStorage BRepGraph_Data::myMeshCache

Cached mesh data storage (algorithm-derived, non-mutating). Holds triangulation/polygon rep references written by BRepGraphMesh. Does NOT trigger markModified() or mutation tracking.

myMeshView

BRepGraph::MeshView BRepGraph_Data::myMeshView {nullptr}

myNextUIDCounter

std::atomic<size_t> BRepGraph_Data::myNextUIDCounter

Initial value:

{
    1}

UID system.

Starts at 1; counter=0 is BRepGraph_UID invalid sentinel.

myPropagationWave

std::atomic<uint32_t> BRepGraph_Data::myPropagationWave {0}

Propagation wave counter. Incremented at the start of each markModified() / markRefModified() call. markParentModified() compares entity.LastPropWave against this to skip already-visited parents in the same propagation wave (O(1) re-visit guard).

myRefsView

BRepGraph::RefsView BRepGraph_Data::myRefsView {nullptr}

myRefUIDToRefId

NCollection_DataMap<BRepGraph_RefUID, BRepGraph_RefId> BRepGraph_Data::myRefUIDToRefId

mutable

Lazy reverse lookup index for reference UIDs.

myRefUIDToRefIdDirty

bool BRepGraph_Data::myRefUIDToRefIdDirty = true

mutable

myRefUIDToRefIdGeneration

uint32_t BRepGraph_Data::myRefUIDToRefIdGeneration = 0

mutable

myRefUIDToRefIdMutex

std::shared_mutex BRepGraph_Data::myRefUIDToRefIdMutex

mutable

myRemoveSubgraphDepth

uint32_t BRepGraph_Data::myRemoveSubgraphDepth = 0

Recursion depth of EditorView::GenOps::RemoveSubgraph. Outermost call (depth==0) triggers a single reverse-index rebuild after cascade so individual cascade-prune steps avoid maintaining per-kind unbinds for every removed node.

myRootProductIds

NCollection_DynamicArray<BRepGraph_ProductId> BRepGraph_Data::myRootProductIds

Root product identifiers: products not referenced by any active occurrence. Maintained incrementally by Editor/EditorView mutations.

myShapesView

BRepGraph::ShapesView BRepGraph_Data::myShapesView {nullptr}

myTopoView

BRepGraph::TopoView BRepGraph_Data::myTopoView {nullptr}

Cached view objects (pointers set to owning BRepGraph in its constructor).

myUIDsView

BRepGraph::UIDsView BRepGraph_Data::myUIDsView {nullptr}

myUIDToNodeId

NCollection_DataMap<BRepGraph_UID, BRepGraph_NodeId> BRepGraph_Data::myUIDToNodeId

mutable

Lazy reverse lookup index for entity UIDs.

myUIDToNodeIdDirty

bool BRepGraph_Data::myUIDToNodeIdDirty = true

mutable

myUIDToNodeIdGeneration

uint32_t BRepGraph_Data::myUIDToNodeIdGeneration = 0

mutable

myUIDToNodeIdMutex
