◆ overrideFileName()

ILIAS\ResourceStorage\Consumer\DownloadMultipleConsumer::overrideFileName ( string $file_name )

Implements ILIAS\ResourceStorage\Consumer\DeliveryConsumer.

Definition at line 105 of file DownloadMultipleConsumer.php.

                                                       : DeliveryConsumer
    {
        $this->zip_file_name = $file_name;
        return $this;
    }

◆ run()

ILIAS\ResourceStorage\Consumer\DownloadMultipleConsumer::run ( )

This runs the actual DeliveryConsumer.

E.g. a DownloadConsumer will pass the Stream of a Ressource to the HTTP-Service and download the file.
