unsigned int OEAtomGetSmallestRingSize(const OEAtomBase *atm)
unsigned int OEAtomGetSmallestRingSize(const OEAtomBase &atm)
Determines the size of the smallest ring that an atom is in. If the atom is not in a ring, i.e. OEAtomBase::IsInRing returns false, the value zero is returned.
Warning
It is not necessary to perform the ring perception by calling OEFindRingAtomsAndBonds function prior to calling OEAtomGetSmallestRingSize function.
