IfcPropertyListValue Class
Syntax
C++
class IfcPropertyListValue : public IfcSimpleProperty;

An IfcPropertyListValue defines a property that has several (numeric or descriptive) values assigned, these values are given by an ordered list.  It defines a property - list value combination for which the property Name, an optional Description,  the optional ListValues with measure type and optionally an Unit are specified. An IfcPropertyListValue is an ordered list of values. All list members must be have the same type.

  • If the Unit attribute is not specified, than the unit is already implied by the type of IfcMeasureValue or IfcDerivedMeasureValue. The associated unit can be found at the IfcUnitAssignment globally defined at the project level (IfcProject.UnitsInContext).
  • If the Unit attribute is specified, the unit assigned by the Unit attribute overrides the globally assigned unit.
