class OENthAtom : public OESystem::OEUnaryPredicate<OEChem::OEAtomBase>
This class represents OENthAtom functor that identifies the Nth atom (OEAtomBase) is the molecule.
The following methods are publicly inherited from OEUnaryPredicate:
The following methods are publicly inherited from OEUnaryFunction:
OENthAtom(unsigned int n, unsigned int start=0)
Constructs the functor with the Nth atom specified by ‘n’ and the starting atom specified by ‘start’.
bool operator()(const OEAtomBase &atom) const
true, if iteration over the atoms in the molecule makes
the ‘atom’ the Nth atom in the molecule starting with the first
atom being the ‘start’ atom.
