+/**
+ * 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.png)
+ *
+ * `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
