  9. * Converts an Observable of {@link Notification} objects into the emissions
  10. * that they represent.
  11. *
  12. * <span class="informal">Unwraps {@link Notification} objects as actual `next`,
  13. * `error` and `complete` emissions. The opposite of {@link materialize}.</span>

  16. *
  17. * `dematerialize` is assumed to operate an Observable that only emits
  18. * {@link Notification} objects as `next` emissions, and does not emit any
  19. * `error`. Such Observable is the output of a `materialize` operation. Those
  20. * notifications are then unwrapped using the metadata they contain, and emitted
  21. * as `next`, `error`, and `complete` on the output Observable.
  22. *
  23. * Use this operator in conjunction with {@link materialize}.
  24. *
  25. * @example <caption>Convert an Observable of Notifications to an actual Observable</caption>
  26. * var notifA = new Rx.Notification('N', 'A');
  27. * var notifB = new Rx.Notification('N', 'B');
  28. * var notifE = new Rx.Notification('E', void 0,
  29. * new TypeError('x.toUpperCase is not a function')
  30. * );
  31. * var materialized = Rx.Observable.of(notifA, notifB, notifE);
  32. * var upperCase = materialized.dematerialize();
  33. * upperCase.subscribe(x => console.log(x), e => console.error(e));
  34. *
  35. * // Results in:
  36. * // A
  37. * // B
  38. * // TypeError: x.toUpperCase is not a function

  43. * @return {Observable} An Observable that emits items and notifications
  44. * embedded in Notification objects emitted by the source Observable.
