DrawingAnnotations

Flat annotation store for a TechnicalDrawing, keyed by UUID.

Extends

• DataMap<string, AnnotationEntry>

Constructors

new DrawingAnnotations()

new DrawingAnnotations(): DrawingAnnotations

Each entry bundles the owning system, the data, and the Three.js group — so a single drawing.annotations.get(uuid) gives full access to all three.

Systems write here when they create or update annotations; consumers read from here or subscribe to system-level events (onCommit, onDelete).

// Get everything for a known UUID
const { system, data, three } = drawing.annotations.get(uuid)!;

// Iterate all annotations owned by a specific system
for (const [uuid, dim] of drawing.annotations.getBySystem(dims)) { ... }

Returns

DrawingAnnotations

Overrides

FRAGS.DataMap<string, AnnotationEntry>.constructor

Methods

getBySystem()

getBySystem<T>(system): Map<string, T>

Returns a snapshot map of uuid → item for all annotations owned by system on this drawing. TypeScript infers the item type from the system's _item declaration marker, avoiding DataMap event variance issues.

Parameters
