       OEGetSmiStringOrder(const OEMolBase &mol,
                           unsigned int flavor = OESMILESFlag::DEFAULT);

Returns an iterator over the heavy atoms of a molecule, in the order in which they appear in the canonical SMILES string. Several variants of SMILES format are supported by using different flavors from the OESMILESFlag namespace.

OEGraphMol mol;

for (OEIter<OEAtomBase> ai = OEGetSmiStringOrder(mol); ai; ++ai)
  cout << ai->GetIdx() << ' ' << OEGetAtomicSymbol(ai->GetAtomicNum()) << endl;
