Detailed Description

Single-level typed iterators over parent definitions via reverse index.

These iterators wrap the NCollection_DynamicArray<TypedIdT> returned by TopoView reverse-index accessors (e.g. Edges().Faces(), Wires().Faces(), Vertices().Edges()). They provide a typed, skip-removed iteration pattern consistent with the forward iterators in BRepGraph_DefsIterator and BRepGraph_RefsIterator.

Usage:

// Traditional iteration:
for (BRepGraph_FacesOfEdge anIt(aGraph, aGraph.Topo().Edges().Faces(anEdgeId));
     anIt.More(); anIt.Next())
{
  const BRepGraph_FaceId aFaceId = anIt.CurrentId();
}
 
// Range-based for:
for (const BRepGraph_FaceId aFaceId :
     BRepGraph_FacesOfEdge(aGraph, aGraph.Topo().Edges().Faces(anEdgeId)))
{
  // ...
}
