Crate ifc_classification 

Borrowed IFC2X3/IFC4/IFC4X3 classification, document, library and association semantics.

Views borrow ifc_model::Model and read every record against the release its header declares (see classification_schema): IFC2X3 TC1, IFC4 ADD2 TC1 or IFC4X3 ADD2. Slot positions, selects, domains and enumerations come from that release’s bundled table, looked up by attribute name. A header declaring several schemas, or one with no bundled table, is refused rather than read as IFC4; a header declaring none (an in-memory model) binds IFC4.

Authoring helpers stage records on a caller-owned ifc_model::Transaction in the same release’s layout, refusing values and entities the release cannot hold. No query performs external I/O.

Functions

associate_classification

Validate and stage an IfcRelAssociatesClassification linking draft.related_objects to target, with OwnerHistory unset.

associate_classification_with_owner_history

associate_classification with a caller-supplied IfcOwnerHistory, which IFC2X3 requires.

associate_document

Validate and stage an IfcRelAssociatesDocument linking draft.related_objects to target, with OwnerHistory unset.

associate_document_with_owner_history

associate_document with a caller-supplied IfcOwnerHistory, which IFC2X3 requires.

associate_library

Validate and stage an IfcRelAssociatesLibrary linking draft.related_objects to target, with OwnerHistory unset.

associate_library_with_owner_history

associate_library with a caller-supplied IfcOwnerHistory, which IFC2X3 requires.

classification_schema

The IFC release model’s classification records are read and written against.

create_classification
