/** |
|
* The Max operator operates on an Observable that emits numbers (or items that can be compared with a provided function), |
|
* and when source Observable completes it emits a single item: the item with the largest value. |
|
* |
|
* <img src="./img/max.png" width="100%"> |
|
* |
|
* @example <caption>Get the maximal value of a series of numbers</caption> |
|
* Rx.Observable.of(5, 4, 7, 2, 8) |
|
* .max() |
|
* .subscribe(x => console.log(x)); // -> 8 |
|
* |
|
* @example <caption>Use a comparer function to get the maximal item</caption> |
|
* interface Person { |
|
* age: number, |
|
* name: string |
|
* } |
|
* Observable.of<Person>({age: 7, name: 'Foo'}, |
|
* {age: 5, name: 'Bar'}, |
|
* {age: 9, name: 'Beer'}) |
|
* .max<Person>((a: Person, b: Person) => a.age < b.age ? -1 : 1) |
|
* .subscribe((x: Person) => console.log(x.name)); // -> 'Beer' |
|
* } |
|
* |
|
* @see {@link min} |
|
* |
|
* @param {Function} [comparer] - Optional comparer function that it will use instead of its default to compare the |
|
* value of two items. |
|
* @return {Observable} An Observable that emits item with the largest value. |
|
* @method max |
