Struct ExternalReferenceRelationship 

pub struct ExternalReferenceRelationship<'m> { /* private fields */ }

Borrowed projection of an IFCEXTERNALREFERENCERELATIONSHIP entity.

Projections handed out by a crate::ClassificationView read against the release the model declares (IFC2X3, IFC4 or IFC4X3); one built with try_new has no model and reads against IFC4, as in 0.2.0.

Implementations

impl<'m> ExternalReferenceRelationship<'m>

pub fn try_new(id: EntityId, entity: &'m Entity) -> ClassificationResult<Self>

Project entity as IFCEXTERNALREFERENCERELATIONSHIP, checking its runtime type; fails with WrongEntityType if it is not.

Without a model there is no header to bind, so the projection reads against IFC4. Use the view’s lookups to read another release.

pub const fn id(self) -> EntityId

Entity id of the underlying instance.

pub const fn entity(self) -> &'m Entity

Borrowed underlying entity record.

impl<'m> ExternalReferenceRelationship<'m>

pub fn name(self) -> ClassificationResult<Option<&'m str>>

Optional relationship name.

pub fn description(self) -> ClassificationResult<Option<&'m str>>

Optional relationship description.

pub fn relating_reference(self) -> ClassificationResult<EntityId>

External reference that applies to the related resources.

pub fn related_resources(self) -> ClassificationResult<Vec<EntityId>>

Resource-level objects carrying this external reference.
