import { Observable } from '../Observable'; import { retry as higherOrder } from '../operators/retry'; /** * 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. * * <img src="./img/retry.png" width="100%"> * * 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`]. * @param {number} count - Number of retry attempts before failing. * @return {Observable} The source Observable modified with the retry logic. * @method retry * @owner Observable */ export function retry<T>(this: Observable<T>, count: number = -1): Observable<T> { return higherOrder(count)(this) as Observable<T>; }
