- def refreshState(newState: Eval[State])(implicit traceContext: TraceContext): Unit
Triggers a refresh of the component's state, using
newStateto determine the new state.Triggers a refresh of the component's state, using
newStateto determine the new state. May return before thenewStatehas been evaluated and the listeners have been poked.Note that listeners need not be poked about every state change; it suffices that they are poked eventually after each state change. So if there are frequent updates to the state, possibly from concurrent calls, then the listeners may never see some intermediate states.
