Inheritance diagram for BRepGraphInc::FaceDef:

Public Types
using	TypeId = BRepGraph_FaceId

Public Types inherited from BRepGraphInc::BaseDef
using	TypeId = BRepGraph_NodeId

Data Fields
BRepGraph_FaceSurfaceRepId	SurfaceRepId
	Owned surface use id.

BRepGraph_FaceTriangulationRepId	TriangulationRepId
	Owned triangulation use id (persistent/imported)

double	Tolerance = 0.0
	Face tolerance.

Data Fields inherited from BRepGraphInc::BaseDef
uint32_t	UID = 0
	Persistent per-kind UID counter value. 0 = invalid sentinel (not yet allocated). Valid UIDs start at 1. Kind is implicit from the concrete struct type (VertexDef, EdgeDef, etc.).

uint32_t	OwnGen = 0
	Own-data mutation counter, incremented ONLY when the entity's own definition fields change (tolerance, point, flags, etc.). NOT incremented by descendant changes. Used by VersionStamp for persistent identity staleness detection.

uint32_t	SubtreeGen = 0
	Subtree mutation counter, incremented when own data OR any descendant data changes. Propagated upward via markParentSubtreeGen(). Used by TransientCache and shape cache for hierarchical freshness.

uint32_t	LastPropWave = 0
	Wave counter from the last propagation that visited this node. Used as a re-visit guard in markParentSubtreeGen() to prevent exponential blowup on diamond topologies. Compared against BRepGraphInc_Storage::myPropagationWave.
