Enums

enum Property

The properties contained are assigned a bit. This can be switched on or off to flag the presence or absence of the property.

Values:

Energy = (1 << 0)

Gradients = (1 << 1)

Hessian = (1 << 2)

Dipole = (1 << 3)

DipoleGradient = (1 << 4)

DipoleMatrixAO = (1 << 5)

DipoleMatrixMO = (1 << 6)

OneElectronMatrix = (1 << 7)

TwoElectronMatrix = (1 << 8)

BondOrderMatrix = (1 << 9)

Functions

constexpr Property operator|(Property v1, Property v2)

Returns a Property object that is the superset of the two properties given as argument.

Allow combination of properties.

constexpr bool operator&(Property v1, Property v2)

Returns a Property object that is the subset of the two properties given as argument.

Allow to check if there is a flag overlap.

class PropertyList

#include <PropertyList.h>

This class defines a list of properties that can be calculated in a single-point calculation.

Public Functions

PropertyList()

Initializes the property enum to be empty, i.e. all switched off.

PropertyList(Property p)

Constructor from properties; not explicit to allow for automatic conversion.

bool containsSubSet(const PropertyList &pl) const

Checks for the presence of a PropertyList given as argument as subset of the current object.

void addProperty(const Property v)

Switches on the bits that are switched on in the argument Property v
