@camera.ui/sdk / observable / BehaviorSubject

Class: BehaviorSubject<T>

Defined in: observable/index.ts:197

Subject seeded with an initial value that always remembers the latest emission. New subscribers receive the current value immediately on subscribe() and then all subsequent values. The current value is also accessible synchronously via value and getValue().
