- * 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>
- *
- * <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.
- * @method dematerialize
- * @owner Observable
