Crate ifc_classification 

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

Views borrow ifc_model::Model and read every record against the release its header declares (see classification_schema): slot positions, selects and domains come from that release’s bundled table. Authoring helpers stage IFC4 records on a caller-owned ifc_model::Transaction. No query performs external I/O.

Functions

associate_classification

Validate and stage an IfcRelAssociatesClassification linking draft.related_objects to target; fails if target is not an IfcClassificationSelect, or on any shared association precondition.

associate_document

Validate and stage an IfcRelAssociatesDocument linking draft.related_objects to target; fails if target is not an IfcDocumentSelect, or on any shared association precondition.

associate_library

Validate and stage an IfcRelAssociatesLibrary linking draft.related_objects to target; fails if target is not an IfcLibrarySelect, or on any shared association precondition.

classification_schema

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

create_classification

Validate and stage one IfcClassification; fails if reference_tokens is Some and empty.

create_classification_reference

Validate and stage one IfcClassificationReference; fails if location/identification/name are all unstated or referenced_source does not resolve to an IfcClassificationReferenceSelect.

create_document

Validate and stage one IfcDocumentInformation; fails on an invalid Confidentiality/Status enumerator, a document_owner/editors entry that is not an IfcActorSelect, or a duplicate/empty editors set.

create_document_reference

Validate and stage one IfcDocumentReference; fails if location/identification/name are all unstated, if name and referenced_document are not exactly one, or if referenced_document is not an IfcDocumentInformation.

create_external_reference_relationship

Validate and stage one IfcExternalReferenceRelationship.

create_library

Validate and stage one IfcLibraryInformation; fails if publisher does not resolve to an IfcActorSelect.

create_library_reference

Validate and stage one IfcLibraryReference; fails if location/identification/name are all unstated or referenced_library is not an IfcLibraryInformation.

relate_documents

Stage an IfcDocumentInformationRelationship.

Type Aliases

ClassificationResult

Result of a classification/document/library query or authoring operation.
