The input is a function `func` with some parameters. The - * last parameter must be a callback function that `func` calls when it is - * done. - * - * The output of `bindCallback` is a function that takes the same parameters - * as `func`, except the last one (the callback). When the output function - * is called with arguments it will return an Observable. If function `func` - * calls its callback with one argument, the Observable will emit that value. - * If on the other hand the callback is called with multiple values the resulting - * Observable will emit an array with said values as arguments. - * - * It is **very important** to remember that input function `func` is not called - * when the output function is, but rather when the Observable returned by the output - * function is subscribed. This means if `func` makes an AJAX request, that request - * will be made every time someone subscribes to the resulting Observable, but not before. - * - * The last optional parameter - `scheduler` - can be used to control when the call - * to `func` happens after someone subscribes to Observable, as well as when results - * passed to callback will be emitted. By default, the subscription to an Observable calls `func` - * synchronously, but using {@link asyncScheduler} as the last parameter will defer the call to `func`, - * just like wrapping the call in `setTimeout` with a timeout of `0` would. If you were to use the async Scheduler - * and call `subscribe` on the output Observable, all function calls that are currently executing - * will end before `func` is invoked. - * - * By default, results passed to the callback are emitted immediately after `func` invokes the callback. - * In particular, if the callback is called synchronously, then the subscription of the resulting Observable - * will call the `next` function synchronously as well. If you want to defer that call, - * you may use {@link asyncScheduler} just as before. This means that by using `Scheduler.async` you can - * ensure that `func` always calls its callback asynchronously, thus avoiding terrifying Zalgo. - * - * Note that the Observable created by the output function will always emit a single value - * and then complete immediately. If `func` calls the callback multiple times, values from subsequent - * calls will not appear in the stream. If you need to listen for multiple calls, - * you probably want to use {@link fromEvent} or {@link fromEventPattern} instead. - * - * If `func` depends on some context (`this` property) and is not already bound, the context of `func` - * will be the context that the output function has at call time. In particular, if `func` - * is called as a method of some objec and if `func` is not already bound, in order to preserve the context - * it is recommended that the context of the output function is set to that object as well. - * - * If the input function calls its callback in the "node style" (i.e. first argument to callback is - * optional error parameter signaling whether the call failed or not), {@link bindNodeCallback} - * provides convenient error handling and probably is a better choice. - * `bindCallback` will treat such functions the same as any other and error parameters - * (whether passed or not) will always be interpreted as regular callback argument. - * - * ## Examples - * - * ### Convert jQuery's getJSON to an Observable API - * ```javascript - * import { bindCallback } from 'rxjs'; - * import * as jQuery from 'jquery'; - * - * // Suppose we have jQuery.getJSON('/my/url', callback) - * const getJSONAsObservable = bindCallback(jQuery.getJSON); - * const result = getJSONAsObservable('/my/url'); - * result.subscribe(x => console.log(x), e => console.error(e)); - * ``` - * - * ### Receive an array of arguments passed to a callback - * ```javascript - * import { bindCallback } from 'rxjs'; - * - * someFunction((a, b, c) => { - * console.log(a); // 5 - * console.log(b); // 'some string' - * console.log(c); // {someProperty: 'someValue'} - * }); - * - * const boundSomeFunction = bindCallback(someFunction); - * boundSomeFunction().subscribe(values => { - * console.log(values) // [5, 'some string', {someProperty: 'someValue'}] - * }); - * ``` - * - * ### Compare behaviour with and without async Scheduler - * ```javascript - * import { bindCallback } from 'rxjs'; - * - * function iCallMyCallbackSynchronously(cb) { - * cb(); - * } - * - * const boundSyncFn = bindCallback(iCallMyCallbackSynchronously); - * const boundAsyncFn = bindCallback(iCallMyCallbackSynchronously, null, Rx.Scheduler.async); - * - * boundSyncFn().subscribe(() => console.log('I was sync!')); - * boundAsyncFn().subscribe(() => console.log('I was async!')); - * console.log('This happened...'); - * - * // Logs: - * // I was sync! - * // This happened... - * // I was async! - * ``` - * - * ### Use bindCallback on an object method - * ```javascript - * import { bindCallback } from 'rxjs'; - * - * const boundMethod = bindCallback(someObject.methodWithCallback); - * boundMethod.call(someObject) // make sure methodWithCallback has access to someObject - * .subscribe(subscriber); - * ``` - * - * @see {@link bindNodeCallback} - * @see {@link from} - * - * @param {function} func A function with a callback as the last parameter. - * @param {SchedulerLike} [scheduler] The scheduler on which to schedule the - * callbacks. - * @return {function(...params: *): Observable} A function which returns the - * Observable that delivers the same values the callback would deliver. - * @name bindCallback - */ -export function bindCallback<T>( - callbackFunc: Function, - resultSelector?: Function|SchedulerLike, - scheduler?: SchedulerLike -): (...args: any[]) => Observable<T> { - if (resultSelector) { - if (isScheduler(resultSelector)) { - scheduler = resultSelector; - } else { - // DEPRECATED PATH - return (...args: any[]) => bindCallback(callbackFunc, scheduler)(...args).pipe( - map((args) => isArray(args) ?
