Class EntityNode

constructor

• new EntityNode(store: IfcStoreBase, expressId: number): EntityNode

  Parameters

  • store: IfcStoreBase
  • expressId: number

  Returns EntityNode

ReadonlyexpressId

description

• get description(): string

  Returns string

globalId

• get globalId(): string

  Returns string

name

• get name(): string

  Returns string

objectType

• get objectType(): string

  Returns string

tag

• get tag(): string

  Returns string

type

• get type(): string

  Returns string

allAttributes

• allAttributes(): { name: string; value: string | number | boolean }[]

  Get all named string/enum attributes for this entity. Uses the IFC schema to determine attribute names per entity type. Skips GlobalId (shown separately), OwnerHistory, and geometry references.

  Returns { name: string; value: string | number | boolean }[]

building

• building(): EntityNode | null

  Returns EntityNode | null

containedIn

• containedIn(): EntityNode | null

  Returns EntityNode | null

containedInAmbiguous

• containedInAmbiguous(): boolean

  True when this element has more than one direct IfcRelContainedInSpatialStructure edge, i.e. containedIn()'s answer (first-declared wins) was a tie-break rather than the only candidate the source file declared (#4311). Duplicate edges naming the SAME structure collapse to one before either method ever sees them (relationship-graph dedupe), so this only fires on genuinely different candidates.

  Returns boolean

contains

• contains(): EntityNode[]

  Returns EntityNode[]

decomposedBy

• decomposedBy(): EntityNode | null

  Returns EntityNode | null

decomposes

• decomposes(): EntityNode[]

  Returns EntityNode[]

definingType

• definingType(): EntityNode | null

  The type object defining this occurrence.

  IfcRelDefinesByType has the type as its relating object, and the parser stores edges relating -> related, so the type is the source and each occurrence the target. Reaching the type from an occurrence is therefore an inverse traversal — matching the element -> type lookups in on-demand-extractors.ts.

  Returns EntityNode | null

filledBy

• filledBy(): EntityNode[]

  The elements filling this opening (doors, windows).

  IfcRelFillsElement is (RelatingOpeningElement, RelatedBuildingElement), so the opening is the relating object and the filler the related one — reaching the filler from the opening is a forward traversal, the same orientation voids() uses to reach the opening from its host.

  Returns EntityNode[]

instances

• instances(): EntityNode[]

  The occurrences defined by this type — forward, from the type source.

  Returns EntityNode[]

properties

• properties(): PropertySet[]

  Returns PropertySet[]

property

• property(psetName: string, propName: string): PropertyValue

  Parameters

  • psetName: string
  • propName: string

  Returns PropertyValue

quantities

• quantities(): QuantitySet[]

  Returns QuantitySet[]

quantity

• quantity(qsetName: string, quantityName: string): number | null

  Parameters

  • qsetName: string
  • quantityName: string

  Returns number | null

storey

• storey(): EntityNode | null

  Returns EntityNode | null

traverse

• traverse(
      relType: RelationshipType,
      depth: number,
      direction?: "forward" | "inverse",
  ): EntityNode[]

  Parameters

  • relType: RelationshipType
  • depth: number
  • Optionaldirection: "forward" | "inverse"

  Returns EntityNode[]

voids

• voids(): EntityNode[]

  Returns EntityNode[]
