|
* Skip the last `count` values emitted by the source Observable. |
|
* |
|
*  |
|
* |
|
* `skipLast` returns an Observable that accumulates a queue with a length |
|
* enough to store the first `count` values. As more values are received, |
|
* values are taken from the front of the queue and produced on the result |
|
* sequence. This causes values to be delayed. |
|
* |
|
* ## Example |
|
* Skip the last 2 values of an Observable with many values |
|
* ```ts |
|
* import { range } from 'rxjs'; |
|
* import { skipLast } from 'rxjs/operators'; |
|
* |
|
* const many = range(1, 5); |
|
* const skipLastTwo = many.pipe(skipLast(2)); |
|
* skipLastTwo.subscribe(x => console.log(x)); |
|
* |
|
* // Results in: |
|
* // 1 2 3 |
|
* ``` |
|
* |
|
* @see {@link skip} |
|
* @see {@link skipUntil} |
|
* @see {@link skipWhile} |
|
* @see {@link take} |
|
* |
|
* @throws {ArgumentOutOfRangeError} When using `skipLast(i)`, it throws |
|
* ArgumentOutOrRangeError if `i < 0`. |
|
* |
|
* @param {number} count Number of elements to skip from the end of the source Observable. |
|
* @returns {Observable<T>} An Observable that skips the last count values |
|
* emitted by the source Observable. |
|
* @method skipLast |
|
* @owner Observable |
