Detailed Description
This is a fixed size datapoint type with the length of 8 bytes.
It is a base class for the following classes:
QKnxActiveEnergyV64- Active energy in Wh.QKnxApparentEnergyV64- Active energy in VAh.QKnxReactiveEnergyV64- Active energy in VARh.
The range for the value is from -9 223 372 036 854 775 808 to 9 223 372 036 854 775 807.

Member Function Documentation
[protected] QKnxElectricalEnergy::QKnxElectricalEnergy(int subType, qint64 value)
Creates a fixed size datapoint with the subtype subType and the value value.
QKnxElectricalEnergy::QKnxElectricalEnergy(qint64 value)
Creates a fixed size datapoint type with the value value.
QKnxElectricalEnergy::QKnxElectricalEnergy()
Creates a fixed size datapoint type with the value set to 0.
[override virtual] bool QKnxElectricalEnergy::isValid() const
Reimplements: QKnxDatapointType::isValid() const.
bool QKnxElectricalEnergy::setValue(qint64 value)
Sets the value of the datapoint type to value.
If the value is outside the allowed range, returns false and does not set the value.
See also value().
qint64 QKnxElectricalEnergy::value() const
Returns the value stored in the datapoint type.
See also setValue().
