Whatever you can call produceNextCallback anywhere :

$reader = new \Rxnet\OnDemand\OnDemandFileReader("./test.csv");
$reader
    ->getObservable()
    ->doOnNext(function ($row) { echo "got row : {$row}" . PHP_EOL; })
    ->subscribeCallback($reader->produceNextCallback());

$reader->produceNext(1);
