OnStateEvent

Marks a function as a handler for state events, indicating that the function should be invoked when a state event is emitted. This annotation is used in conjunction with the OnMessage annotation to specify the type of message and default function name.

The value parameter allows specifying one or more aggregate names to which this state event handler applies.

Examples:

    @OnStateEvent
    fun onStateEvent(changed: Changed, state: State) {
         //...
     }

Remote Context:

    @OnStateEvent
    fun onStateEvent(changed: Changed, stateRecord: StateRecord) {
      val state = stateRecord.toState<StateData>()
         //...
     }
