TimerTask interface

Retourné à partir de durableClient.createTimer(Date) si l’appel n’est pas yield-ed. Représente un minuteur en attente. Pour plus d’informations, consultez la documentation sur tâche.

Tous les minuteurs en attente doivent être terminés ou annulés pour qu’une orchestration se termine.

exemple de

Annuler un minuteur

// calculate expiration date
const timeoutTask = context.df.createTimer(expirationDate);

// do some work

if (!timeoutTask.isCompleted) {
    // An orchestration won't get marked as completed until all its scheduled
    // tasks have returned, or been cancelled. Therefore, it is important
    // to cancel timers when they're no longer needed
    timeoutTask.cancel();
}

exemple de

Créer un délai d’expiration

const now = Date.now();
const expiration = new Date(now.valueOf()).setMinutes(now.getMinutes() + 30);

const timeoutTask = context.df.createTimer(expirationDate);
const otherTask = context.df.callActivity("DoWork");

const winner = yield context.df.Task.any([timeoutTask, otherTask]);

if (winner === otherTask) {
    // do some more work
}

if (!timeoutTask.isCompleted) {
    // An orchestration won't get marked as completed until all its scheduled
    // tasks have returned, or been cancelled. Therefore, it is important
    // to cancel timers when they're no longer needed
    timeoutTask.cancel();
