BRepGraphInc::EdgeDef Struct Reference

Edge entity: parameter range, boundary vertices. Geometry (curve, polygon) accessed via owned use records. Degeneracy, closure, SameRange, and SameParameter are derived from current topology and geometry via BRepGraph_CacheDerivedState. More...

Data Fields
BRepGraph_EdgeCurve3DRepId	Curve3DRepId

	Tolerance from BRep_TEdge.

	Start vertex reference.

	End vertex reference.

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.

Detailed Description

Edge entity: parameter range, boundary vertices. Geometry (curve, polygon) accessed via owned use records. Degeneracy, closure, SameRange, and SameParameter are derived from current topology and geometry via BRepGraph_CacheDerivedState.
