| /** |
| * Converts an Observable of {@link Notification} objects into the emissions |
| * that they represent. |
| * |
| * <span class="informal">Unwraps {@link Notification} objects as actual `next`, |
| * `error` and `complete` emissions. The opposite of {@link materialize}.</span> |
| * |
| *  |
| * |
| * `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 |
| * Convert an Observable of Notifications to an actual Observable |
| * ```ts |
| * import { of, Notification } from 'rxjs'; |
| * import { dematerialize } from 'rxjs/operators'; |
| * |
| * const notifA = new Notification('N', 'A'); |
| * const notifB = new Notification('N', 'B'); |
| * const notifE = new Notification('E', undefined, |
| * new TypeError('x.toUpperCase is not a function') |
| * ); |
| * const materialized = of(notifA, notifB, notifE); |
| * const upperCase = materialized.pipe(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. |
| * @method dematerialize |
| * @owner Observable |
