Methods

extractPropertiesOnDemand

extractPropertiesOnDemand(
store: IfcDataStore,
entityId: number,
): { globalId?: string; name: string; properties: ExtractedProperty[] }[]
Extract properties for a single entity ON-DEMAND Parses only what's needed from the source buffer - instant results.
Parameters
- store: IfcDataStore
- entityId: number
Returns { globalId?: string; name: string; properties: ExtractedProperty[] }[]

extractQuantitiesOnDemand

extractQuantitiesOnDemand(
    store: IfcDataStore,
    entityId: number,
    view?: MetadataReadView,
): { globalId?: string; name: string; quantities: CollectedQuantity[] }[]
Extract quantities for a single entity ON-DEMAND Parses only what's needed from the source buffer - instant results.
Parameters
- store: IfcDataStore
- entityId: number
- Optionalview: MetadataReadView
Returns { globalId?: string; name: string; quantities: CollectedQuantity[] }[]

parseLite

parseLite(
    buffer: ArrayBuffer | SharedArrayBuffer,
    entityRefs: EntityRef[],
    options?: {
        deferPropertyAtomIndex?: boolean;
        onDiagnostic?: (message: string) => void;
        onProgress?: (progress: { percent: number; phase: string }) => void;
        onSpatialReady?: (partialStore: IfcDataStore) => void;
        yieldIntervalMs?: number;
    },
): Promise<IfcDataStore>
Parse IFC file into columnar data store

Uses fast semicolon-based scanning with on-demand property extraction. Properties are parsed lazily when accessed, not upfront. This provides instant UI responsiveness even for very large files.
Parameters
- buffer: ArrayBuffer | SharedArrayBuffer
- entityRefs: EntityRef[]
- Optionaloptions: {
      deferPropertyAtomIndex?: boolean;
      onDiagnostic?: (message: string) => void;
      onProgress?: (progress: { percent: number; phase: string }) => void;
      onSpatialReady?: (partialStore: IfcDataStore) => void;
      yieldIntervalMs?: number;
  }
Returns Promise<IfcDataStore>
