Symfony 2 文件上传。如何在 move() 上抛出异常

Question

阅读 symfony 文档，http://symfony.com/doc/current/cookbook/doctrine/file_uploads.html

// you must throw an exception here if the file cannot be moved
// so that the entity is not persisted to the database
// which the UploadedFile move() method does automatically
$this->file->move($this->getUploadRootDir(), $this->path);

如果我这样做了

if ($this->file->move(...)) 

我遇到了一个错误

可捕获的致命错误：类 Symfony\Component\HttpFoundation\File\File 的对象无法在 .../xxx.php 第 96 行中转换为布尔值

看源码：https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpFoundation/File/File.php#L108

好像已经抛出异常了。
