Typedefs
using	BRepGraphInc::VertexInstance = Instance<BRepGraph_VertexId>
using	BRepGraphInc::CoEdgeInstance = Instance<BRepGraph_CoEdgeId>
using	BRepGraphInc::FaceInstance = Instance<BRepGraph_FaceId>

using	BRepGraphInc::CompSolidInstance = Instance<BRepGraph_CompSolidId>
using	BRepGraphInc::ProductInstance = Instance<BRepGraph_ProductId>
using	BRepGraphInc::NodeInstance = Instance<BRepGraph_NodeId>
	NodeInstance is Instance<BRepGraph_NodeId>. Returned by BRepGraph_ChildExplorer and BRepGraph_ParentExplorer with accumulated transforms from traversal root to the current node. Implicitly convertible from any typed Instance via BRepGraph_NodeId::Typed implicit conversion to BRepGraph_NodeId.

Detailed Description

Unified lightweight container binding a node identity with placement.

Instance<T> is the BRepGraph analogue of TopoDS_Shape: a lightweight value type that bundles a definition id with its location and orientation in context.

Supports C++17 structured bindings (aggregate type):

for (auto [aDefId, aLoc, anOri] : BRepGraph_ChildExplorer(aGraph, aRoot, Kind::Face))
{
  // ...
}
