However when called recursively, that is when inside the scheduled task, * another task is scheduled with queue scheduler, instead of executing immediately as well, * that task will be put on a queue and wait for current one to finish. * * This means that when you execute task with `queue` scheduler, you are sure it will end * before any other task scheduled with that scheduler will start. * * @examples Schedule recursively first, then do something * * Rx.Scheduler.queue.schedule(() => { * Rx.Scheduler.queue.schedule(() => console.log('second')); // will not happen now, but will be put on a queue * * console.log('first'); * }); * * // Logs: * // "first" * // "second" * * * @example Reschedule itself recursively * * Rx.Scheduler.queue.schedule(function(state) { * if (state !== 0) { * console.log('before', state); * this.schedule(state - 1); // `this` references currently executing Action, * // which we reschedule with new state * console.log('after', state); * } * }, 0, 3); * * // In scheduler that runs recursively, you would expect: * // "before", 3 * // "before", 2 * // "before", 1 * // "after", 1 * // "after", 2 * // "after", 3 * * // But with queue it logs: * // "before", 3 * // "after", 3 * // "before", 2 * // "after", 2 * // "before", 1 * // "after", 1 * * * @static true * @name queue * @owner Scheduler */ export const queue = new QueueScheduler(QueueAction); //# sourceMappingURL=queue.js.map
