- `getStateImpl<StateNames>(...stateNames: StateNames): Promise<ObjectWithKeysFromStringArray<StateNames>>` — Adapter-specific state lookup implementation.
- `removeState(stateName: string): Promise<void>` — Remove one state value by name.
- `removeStateImpl(stateName: string): Promise<void>` — Adapter-specific state removal implementation.
- `setState(stateName: string, stateValue: unknown): Promise<void>` — Store or replace one state value.
