TimerTask interface

從 DurableClient傳回。如果呼叫不是 createTimer(Date)-ed，yield。 表示擱置的定時器。 如需詳細資訊，請參閱 工作 檔。

所有擱置定時器都必須完成或取消，協調流程才能完成。

範例

取消定時器

// 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();
}

範例

建立逾時

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();
}
