What a property actually states.

One variant per concrete IfcProperty subtype in IFC4. A file stating a subtype this crate does not model yields PropertyValue::Unsupported carrying the type name, so an unknown property is reported rather than silently dropped from its set.

Variants

Single

IfcPropertySingleValue: one measure, optionally with a unit.

Fields

value: Option<MeasureValue>

The nominal value. None when the file omits it, which is legal.

unit: Option<EntityId>

IfcNamedUnit/IfcDerivedUnit override for this property.

Enumerated

IfcPropertyEnumeratedValue: chosen constants plus their enumeration.

Fields

values: Vec<MeasureValue>

The selected values.

enumeration: Option<EntityId>

The IfcPropertyEnumeration they were selected from.

Bounded

IfcPropertyBoundedValue: a range, optionally with a set point.

Fields

upper: Option<MeasureValue>

Slot 2. Named explicitly because the schema order is upper-first.

lower: Option<MeasureValue>

Slot 3.

set_point: Option<MeasureValue>

Slot 5.

unit: Option<EntityId>

Slot 4.

List

IfcPropertyListValue: an ordered list of measures.

Fields

values: Vec<MeasureValue>

The values, in file order. Order is meaningful in a LIST.

unit: Option<EntityId>

Unit shared by every entry.

Table

IfcPropertyTableValue: a defining/defined value mapping.

Fields

defining: Vec<MeasureValue>

The x column.

defined: Vec<MeasureValue>

The y column.

interpolation: Option<Arc<str>>

How to interpolate between rows, when stated.

Reference

IfcPropertyReferenceValue: a pointer to another entity.

Fields

usage: Option<Arc<str>>

What the reference is for.

reference: Option<EntityId>

The referenced entity.

Complex

IfcComplexProperty: nested properties under a usage name.

Fields

usage: Option<Arc<str>>

The grouping name.

properties: Vec<Property>

Contained properties, in file order.

Unsupported

A concrete IfcProperty subtype this crate does not model.

Fields

type_name: Arc<str>

The declared type, upper-cased.
