/** |
|
* Returns an Observable that mirrors the source Observable with the exception of an `error`. If the source Observable |
|
* calls `error`, this method will resubscribe to the source Observable for a maximum of `count` resubscriptions (given |
|
* as a number parameter) rather than propagating the `error` call. |
|
* |
|
*  |
|
* |
|
* Any and all items emitted by the source Observable will be emitted by the resulting Observable, even those emitted |
|
* during failed subscriptions. For example, if an Observable fails at first but emits [1, 2] then succeeds the second |
|
* time and emits: [1, 2, 3, 4, 5] then the complete stream of emissions and notifications |
|
* would be: [1, 2, 1, 2, 3, 4, 5, `complete`]. |
|
* |
|
* ## Example |
|
* ```ts |
|
* import { interval, of, throwError } from 'rxjs'; |
|
* import { mergeMap, retry } from 'rxjs/operators'; |
|
* |
|
* const source = interval(1000); |
|
* const example = source.pipe( |
|
* mergeMap(val => { |
|
* if(val > 5){ |
|
* return throwError('Error!'); |
|
* } |
|
* return of(val); |
|
* }), |
|
* //retry 2 times on error |
|
* retry(2) |
|
* ); |
|
* |
|
* const subscribe = example.subscribe({ |
|
* next: val => console.log(val), |
|
* error: val => console.log(`${val}: Retried 2 times then quit!`) |
|
* }); |
|
* |
|
* // Output: |
|
* // 0..1..2..3..4..5.. |
|
* // 0..1..2..3..4..5.. |
|
* // 0..1..2..3..4..5.. |
|
* // "Error!: Retried 2 times then quit!" |
|
* ``` |
|
* |
|
* @param {number} count - Number of retry attempts before failing. |
|
* @return {Observable} The source Observable modified with the retry logic. |
|
* @method retry |
|
* @owner Observable |
