| * Delays the emission of items from the source Observable by a given timeout or |
| * until a given Date. |
| * |
| * <span class="informal">Time shifts each item by some specified amount of |
| * milliseconds.</span> |
| * |
| * <img src="./img/delay.png" width="100%"> |
| * |
| * If the delay argument is a Number, this operator time shifts the source |
| * Observable by that amount of time expressed in milliseconds. The relative |
| * time intervals between the values are preserved. |
| * |
| * If the delay argument is a Date, this operator time shifts the start of the |
| * Observable execution until the given date occurs. |
| * |
| * @example <caption>Delay each click by one second</caption> |
| * var clicks = Rx.Observable.fromEvent(document, 'click'); |
| * var delayedClicks = clicks.delay(1000); // each click emitted after 1 second |
| * delayedClicks.subscribe(x => console.log(x)); |
| * |
| * @example <caption>Delay all clicks until a future date happens</caption> |
| * var clicks = Rx.Observable.fromEvent(document, 'click'); |
| * var date = new Date('March 15, 2050 12:00:00'); // in the future |
| * var delayedClicks = clicks.delay(date); // click emitted only after that date |
| * delayedClicks.subscribe(x => console.log(x)); |
| * |
| * @see {@link debounceTime} |
| * @see {@link delayWhen} |
| * |
| * @param {number|Date} delay The delay duration in milliseconds (a `number`) or |
| * a `Date` until which the emission of the source items is delayed. |
| * @param {Scheduler} [scheduler=async] The IScheduler to use for |
| * managing the timers that handle the time-shift for each item. |
| * @return {Observable} An Observable that delays the emissions of the source |
| * Observable by the specified timeout or Date. |
