A property template: what one property should look like.

Every attribute of both template entities has a field; the ones the entity does not declare are None (or empty). Enumeration constants are as written in the file, without their dots.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: EntityId

The entity.

name: Option<Arc<str>>

Name: the property name this template governs.

description: Option<Arc<str>>

Description.

kind: PropertyTemplateKind

Simple or complex.

template_type: Option<Arc<str>>

TemplateType: an IfcSimplePropertyTemplateTypeEnum constant such as P_SINGLEVALUE for a simple template, an IfcComplexPropertyTemplateTypeEnum constant (P_COMPLEX, Q_COMPLEX) for a complex one.

This states which IfcProperty or IfcPhysicalQuantity subtype an instance should use, so it is the link between a template and the property families in pset.

primary_measure: Option<Arc<str>>

PrimaryMeasureType, e.g. IfcLengthMeasure (simple only).

secondary_measure: Option<Arc<str>>

SecondaryMeasureType, used by bounded and table values (simple only).

enumerators: Option<EntityId>

Enumerators: the IfcPropertyEnumeration an enumerated value selects from (simple only).

primary_unit: Option<EntityId>

PrimaryUnit (simple only).

secondary_unit: Option<EntityId>

SecondaryUnit, the defined unit of a table value (simple only).

expression: Option<Arc<str>>

Expression: a table’s correlation or a quantity’s formula (simple only).

access_state: Option<Arc<str>>

AccessState, an IfcStateEnum constant such as READONLY (simple only).

usage_name: Option<Arc<str>>

UsageName (complex only).

templates: Vec<PropertyTemplate>

HasPropertyTemplates, in file order (complex only; empty when $).

Members the traversal refuses (cycle, depth, budget, absent entity, non-template) are left out; the checked readers report each one.
