class Ifc4x2::IfcQuantityCount : public Ifc4x2::IfcPhysicalSimpleQuantity

IfcQuantityCount is a physical quantity that defines a derived count measure to provide an element’s physical property. It is normally derived from the physical properties of the element under the specific measure rules given by a method of measurement.

EXAMPLE An radiator may be measured according to its number of coils. The actual counting method depends on the method of measurement used.

HISTORY New entity in IFC2x. It replaces the calcXxx attributes used in previous IFC Releases.

Public Types

Public Functions

double CountValue() const

Count measure value of this quantity.

void setCountValue(double v)
bool hasFormula() const

Whether the optional attribute Formula is defined for this IfcQuantityCount.

std::string Formula() const

A formula by which the quantity has been calculated. It can be assigned in addition to the actual value of the quantity. Formulas could be mathematic calculations (like width x height), database links, or a combination. The formula is for informational purposes only.
