Columnar data structures for IFClite. Provides TypedArray-based storage for IFC entities, properties, quantities, and relationships.

Installation

npm install @ifc-lite/data

Quick Start

import { StringTableBuilder, EntityTableBuilder, RelationshipGraphBuilder } from '@ifc-lite/data';
import type { EntityTable, RelationshipGraph } from '@ifc-lite/data';

// String interning for efficient storage
const strings = new StringTableBuilder();
const id = strings.intern('IFCWALL');

// Columnar entity storage (builder pattern)
const entityBuilder = new EntityTableBuilder();
// ... add entities ...
const entities: EntityTable = entityBuilder.build();

// Relationship graph (builder pattern)
const graphBuilder = new RelationshipGraphBuilder();
// ... add relationships ...
const graph: RelationshipGraph = graphBuilder.build();

Features

• Columnar (TypedArray) storage for entities, properties, and quantities
• String table with interning for memory efficiency
• Relationship graph with typed edges
• IFC type enum for fast type comparisons
• Spatial hierarchy representation
