    QPdfFile is a means of passing a PDF file along with the associated
    QPdfDocument together into QPdfIOHandler::load(QIODevice *device) so that
    QPdfIOHandler does not need to construct its own redundant QPdfDocument
    instance. If it succeeds in casting the QIODevice to a QPdfFile, it is
    expected to use the QPdfDocument operations for all I/O, and thus the
    normal QFile I/O functions are not needed for that use case.
