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. | |
