+ *
+ * Returns an Observable that emits items based on applying a function that you
+ * supply to each item emitted by the source Observable, where that function
+ * returns an (so-called "inner") Observable. When it projects a source value to
+ * an Observable, the output Observable begins emitting the items emitted by
+ * that projected Observable. However, `exhaustMap` ignores every new projected
+ * Observable if the previous projected Observable has not yet completed. Once
+ * that one completes, it will accept and flatten the next projected Observable
+ * and repeat this process.
+ *
+ * @example <caption>Run a finite timer for each click, only if there is no currently active timer</caption>
+ * var clicks = Rx.Observable.fromEvent(document, 'click');
+ * var result = clicks.exhaustMap((ev) => Rx.Observable.interval(1000).take(5));
+ * result.subscribe(x => console.log(x));
+ *
+ * @see {@link concatMap}
+ * @see {@link exhaust}

+ *
+ * @param {function(value: T, ?index: number): ObservableInput} project A function
+ * that, when applied to an item emitted by the source Observable, returns an
+ * Observable.
+ * @param {function(outerValue: T, innerValue: I, outerIndex: number, innerIndex: number): any} [resultSelector]
+ * A function to produce the value on the output Observable based on the values
+ * and the indices of the source (outer) emission and the inner Observable
+ * emission. The arguments passed to this function are:
+ * - `outerValue`: the value that came from the source
+ * - `innerValue`: the value that came from the projected Observable
+ * - `outerIndex`: the "index" of the value that came from the source
+ * - `innerIndex`: the "index" of the value from the projected Observable
+ * @return {Observable} An Observable containing projected Observables
+ * of each item of the source, ignoring projected Observables that start before
+ * their preceding Observable has completed.
+ * @method exhaustMap
+ * @owner Observable
