Detailed Description

Single-level typed iterators over parent definitions via relation lists.

These iterators wrap parent relation containers returned by TopoView accessors, or derive parent definitions from const relation storage such as EdgeRelations::CoEdgeIds. 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, anEdgeId); anIt.More(); anIt.Next())
{
  const BRepGraph_FaceId aFaceId = anIt.CurrentId();
}
 
// Range-based for:
for (const BRepGraph_FaceId aFaceId : BRepGraph_FacesOfEdge(aGraph, anEdgeId))
{
  // ...
}
