/**
|
|
* 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 <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
