Struct ResourceView 

pub struct ResourceView<'m, 's> { /* private fields */ }

Borrowed, schema-resolved entry point for the bounded IFC4 resource slice: pairs a model with the schema selected for it and exposes per-entity projection and query methods.

Implementations

impl<'m, 's> ResourceView<'m, 's>

pub fn allocation(&self, id: EntityId) -> ResourceResult<ResourceAllocation>

Projects an IfcRelAssignsToResource relation by entity id.

pub fn allocations_for( &self, resource: EntityId, ) -> ResourceResult<Vec<ResourceAllocation>>

Every IfcRelAssignsToResource relation naming this resource as RelatingResource, in ancestor order.

impl<'m, 's> ResourceView<'m, 's>

pub fn parent_resource( &self, child: EntityId, ) -> ResourceResult<Option<EntityId>>

Return the authored construction-resource parent, if any.

pub fn direct_members(&self, parent: EntityId) -> ResourceResult<Vec<EntityId>>

Return direct authored members in relation/LIST order.

pub fn descendants( &self, root: EntityId, budget: Budget, ) -> ResourceResult<Vec<EntityId>>

Return depth-first authored descendants within explicit limits.

impl<'m, 's> ResourceView<'m, 's>

pub fn resource_type( &self, id: EntityId, ) -> ResourceResult<ConstructionResourceType<'m, 's>>

Projects a resource-type catalog entry by entity id.

pub fn assigned_resource_type( &self, occurrence: EntityId, ) -> ResourceResult<Option<EntityId>>

Resolves the IfcConstructionResourceType assigned to a construction resource occurrence through IfcRelDefinesByType, if any.

IfcTypeObject.Types is an inverse SET [0:1]: an occurrence may be typed by at most one relation. A second authored relation naming the same occurrence is a modeling defect, reported as a typed refusal rather than silently picking the first or last match.

impl<'m, 's> ResourceView<'m, 's>

pub fn simple_quantity( &self, id: EntityId, ) -> ResourceResult<SimpleQuantity<'m, 's>>

Projects an IfcPhysicalSimpleQuantity by entity id.

pub fn complex_quantity( &self, id: EntityId, ) -> ResourceResult<ComplexQuantity<'m, 's>>

Projects an IfcPhysicalComplexQuantity by entity id.

impl<'m, 's> ResourceView<'m, 's>

pub fn new(model: &'m Model, schema: &'s Schema) -> ResourceResult<Self>

Builds a view over model using an explicit schema, failing if schema is not IFC4 or IFC4X3, or does not match the model’s declared FILE_SCHEMA token.

pub fn schema(&self) -> &'s Schema

The bundled schema this view resolves attributes against.

pub fn resource( &self, id: EntityId, ) -> ResourceResult<ConstructionResource<'m, 's>>

Projects a concrete IfcConstructionResource occurrence by entity id.

pub fn resource_time( &self, id: EntityId, ) -> ResourceResult<ResourceTime<'m, 's>>

Projects an IfcResourceTime by entity id.

impl<'m> ResourceView<'m, 'static>

pub fn for_model(model: &'m Model) -> ResourceResult<Self>

Selects the bundled schema matching the model’s declared FILE_SCHEMA token (IFC4 ADD2 TC1 or IFC4X3 ADD2), failing if the header names no schema, more than one, or an unsupported one.

impl<'m, 's> ResourceView<'m, 's>

pub fn organization_relationship( &self, id: EntityId, ) -> ResourceResult<OrganizationRelationship<'m, 's>>

Projects an IfcOrganizationRelationship by entity id.

impl<'m, 's> ResourceView<'m, 's>

pub fn person(&self, id: EntityId) -> ResourceResult<Person<'m, 's>>

Projects an IfcPerson by entity id.

pub fn organization(&self, id: EntityId) -> ResourceResult<Organization<'m, 's>>

Projects an IfcOrganization by entity id.

pub fn actor_role(&self, id: EntityId) -> ResourceResult<ActorRole<'m, 's>>

Projects an IfcActorRole by entity id.

pub fn person_and_organization( &self, id: EntityId, ) -> ResourceResult<PersonAndOrganization<'m, 's>>

Projects an IfcPersonAndOrganization by entity id.

impl<'m, 's> ResourceView<'m, 's>

pub fn inventory_items( &self, inventory: EntityId, ) -> ResourceResult<Vec<EntityId>>

Members of an IfcInventory group, authored order, via IfcRelAssignsToGroup.RelatingGroup.

IfcGroup.IsGroupedBy is SET [0:?]: an inventory may be named by several assignment relations. Members from every authored relation are concatenated in relation-then-list order; duplicates across relations are preserved verbatim rather than deduplicated, since the schema does not require assignment relations to be disjoint.

impl<'m, 's> ResourceView<'m, 's>

pub fn inventory(&self, id: EntityId) -> ResourceResult<Inventory<'m, 's>>

Projects an IfcInventory by entity id.
