Classes

DiagramOutlineView

ts
Copy
class DiagramOutlineView

Methods

• constructor(container: HTMLElement, options: OutlineViewOptions = {})
• getElement(): HTMLElement — The hidden region, for tests and hosts that want to relocate it.
• getRebuildCount(): number — How many times the DOM has actually been rebuilt. The thrash proof.
• getOutline(): DiagramOutline | null — The outline currently mirrored (null before the first update).
• update(diagram: DiagramLike | undefined): boolean — Sync the mirror to the model. Cheap and idempotent: returns false — having touched no DOM — when the topology-relevant signature is unchanged.
• dispose(): void

FocusContainmentController

ts
Copy
class FocusContainmentController

Methods

• constructor(viewport: ViewportController, options: FocusContainmentOptions = {})
• isFullyVisible(bounds: Rectangle, padding = this.padding): boolean — Is bounds fully inside the padded visible box? The predicate the whole card turns on — and the one a test can assert directly.
• paddedViewBox(padding = this.padding): Rectangle — The visible world box, deflated by padding CSS pixels on every side.
• plan(bounds: Rectangle, padding = this.padding): ContainmentResult — Compute what would have to happen to bring bounds fully into view — WITHOUT touching the camera. Pure: this is what the tests assert, and what ensureVisible then applies.
• ensureVisible(bounds: Rectangle, padding = this.padding): ContainmentResult — Bring bounds fully into view. Returns what it did — 'none' when the element was already visible, which is the common case and costs nothing.
• isAnimating(): boolean — True while a containment pan is animating.
• stop(): void — Cancel any in-flight pan.
• dispose(): void

LiveRegionController

ts
Copy
class LiveRegionController

Methods

• constructor(container: HTMLElement, options: LiveRegionOptions = {})
• getElement(politeness: Politeness): HTMLElement — The live elements, for tests and for hosts that relocate them.
• getMessage(politeness: Politeness): string — What the region currently says.
• getSpeakCount(): number — How many times we have actually written to the DOM. The thrash proof.
• announce(message: string, politeness: Politeness = 'polite', force = false): boolean — Announce. Returns true if the message will be spoken, false if it was suppressed as a duplicate.
• announceError(message: string): boolean — Errors and validation failures. Always assertive, never coalesced.
• flushPending(): void — Speak any coalesced message immediately.
• clear(): void — Clear both regions (e.g. on blur) without announcing anything.
• dispose(): void
