| //NOTA: en función del directorio de batch y del file puesto en el script, se invoca a este método con el folder y el file que se ha encontrado por cada iteración. | ||
| // en este caso eso no es necesario, porque se trata de cargar desde un servicio. | ||
| // habria que definir el destino del batch como un "service" que habría que inventárselo. En ese service habría que definir lo necesario para la conexión, en este caso al DMOJ. | ||
| // se podria lanzar excepción si se intenta hacer cualquier cosa dentro de un "service" que no sea el copy_detector | ||
| // en un futuro podría interesar conectarse a un servicio remoto, descargar todo lo descargable de allí en local y empezar a lanzar un batch (como Moodle por ejemplo). | ||
|
|
||
| //ALT: como alternativa, se puede usar el INIT para descargar todas las entregas del DMOJ de un concurso. | ||
| // luego, basta con pasarle el anticopia de código fuente a esas carpetas generadas con el modo batch tradicional. | ||
| // esta opción parece más sencilla y factible. | ||
