* Creates an Observable that emits no items to the Observer and immediately |

|
* This static operator is useful for creating a simple Observable that only |
|
* emits the error notification. It can be used for composing with other |
|
* Observables, such as in a {@link mergeMap}. |
|
* |
|
* @example <caption>Emit the number 7, then emit an error.</caption> |
|
* var result = Rx.Observable.throw(new Error('oops!')).startWith(7); |
|
* result.subscribe(x => console.log(x), e => console.error(e)); |
|
* |
|
* @example <caption>Map and flatten numbers to the sequence 'a', 'b', 'c', but throw an error for 13</caption> |
|
* var interval = Rx.Observable.interval(1000); |
|
* var result = interval.mergeMap(x => |
|
* x === 13 ? |
|
* Rx.Observable.throw('Thirteens are bad') : |
|
* Rx.Observable.of('a', 'b', 'c') |
|
* ); |
|
* result.subscribe(x => console.log(x), e => console.error(e)); |

* @see {@link create} |
|
* @see {@link empty} |
|
* @see {@link never} |
|
* @see {@link of} |
|
* |
|
* @param {any} error The particular Error to pass to the error notification. |
|
* @param {Scheduler} [scheduler] A {@link IScheduler} to use for scheduling |
|
* the emission of the error notification. |
|
* @return {Observable} An error Observable: emits only the error notification |
|
* using the given error argument. |
