factor

)

Allows to specify the applied damping factor.

Parameters

factor

The damping factor to apply.

Note

The default damping factor is specified by the constant PEOESigmaChargeCalculator::DEF_DAMPING_FACTOR.

getDampingFactor()

calculate()

void CDPL::MolProp::PEOESigmaChargeCalculator::calculate

(

const Chem::MolecularGraph &

molgraph

)

Calculates the sigma charges and electronegativities of the atoms in the molecular graph molgraph by the PEOE method.

Parameters

molgraph

The molecular graph for which to perform the calculations.

getCharge()

idx

)

const

Returns the calculated sigma charge of the atom with index idx.

Parameters

idx	The index of the atom for which to return the charge.

Exceptions

Base::IndexError

If idx is not in the range [0, NA - 1] where NA is the number of atoms of the molecular graph for which the calculations have been performed.

getElectronegativity()

double CDPL::MolProp::PEOESigmaChargeCalculator::getElectronegativity

(

std::size_t

idx

)
