abstract fun saveState(): EngineSessionState (source)

Saves and returns the engine state. Engine implementations are not required to persist the state anywhere else than in the returned map. Engines that already provide a serialized state can use a single entry in this map to provide this state. The only requirement is that the same map can be used to restore the original state. See restoreState and the specific engine implementation for details.
