Takes each of the most * recent values from each collected inner Observable as arguments, in order. * @return {Observable} An Observable of projected results or arrays of recent * values. * @method combineAll * @owner Observable */ export function combineAll(project) { return higherOrder(project)(this); } //# sourceMappingURL=combineAll.js.map
