/**
|
|
* 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
