Detailed Description

Iterator over registered layers in a BRepGraph_LayerRegistry.

Provides zero-allocation iteration with OCCT More()/Next()/Value() pattern and STL range-for via begin()/end().

// Range-for:
for (const occ::handle<BRepGraph_Layer>& aLayer :
BRepGraph_LayerIterator(aGraph.LayerRegistry()))
  doSomething(aLayer);
 
// Traditional:
for (BRepGraph_LayerIterator anIt(aGraph.LayerRegistry()); anIt.More(); anIt.Next())
  doSomething(anIt.Value());
