Ticket #1236 (new enhancement)
|Reported by:||strk||Owned by:||strk|
TopoGeometry objects are references into a topology's structure. Such references may become dangling if the referee is destroyed.
Hierarchical TopoGeometry objects may be defined to be formed by overlapping lower-level compoments. Such composition should likely be also seen as an invalidity.
Non-hierarchical TopoGeometry objects may refer to missing primitives (corrupted topology).
Beside these structural invalidities there's likely no way for a TopoGeomety?-derived Geometry to be invalid.
