| * Converts an Observable of {@link Notification} objects into the emissions |
| * that they represent. |
| * |
| * <span class="informal">Unwraps {@link Notification} objects as actual `next`, |

| * <img src="./img/dematerialize.png" width="100%"> |
| * |
| * `dematerialize` is assumed to operate an Observable that only emits |
| * {@link Notification} objects as `next` emissions, and does not emit any |
| * `error`. Such Observable is the output of a `materialize` operation. Those |
| * notifications are then unwrapped using the metadata they contain, and emitted |
| * as `next`, `error`, and `complete` on the output Observable. |
| * |
| * Use this operator in conjunction with {@link materialize}. |
| * |
| * @example <caption>Convert an Observable of Notifications to an actual Observable</caption> |
| * var notifA = new Rx.Notification('N', 'A'); |
| * var notifB = new Rx.Notification('N', 'B'); |
| * var notifE = new Rx.Notification('E', void 0, |
| * new TypeError('x.toUpperCase is not a function') |
| * ); |
| * var materialized = Rx.Observable.of(notifA, notifB, notifE); |
| * var upperCase = materialized.dematerialize(); |
| * upperCase.subscribe(x => console.log(x), e => console.error(e)); |
| * |
| * // Results in: |
| * // A |
| * // B |
| * // TypeError: x.toUpperCase is not a function |
| * |
| * @see {@link Notification} |
| * @see {@link materialize} |
| * |
| * @return {Observable} An Observable that emits items and notifications |
| * embedded in Notification objects emitted by the source Observable. |
