werkzeug.wsgi.FileWrapper

This class can be used to convert a :class:`file`-like object into an iterable. It yields `buffer_size` blocks until the file is fully read. You should not use this class directly but rather use the :func:`wrap_file` function that uses the WSGI server's file wrapper support if it's available. .. versionadded:: 0.5 If you're using this object together with a :class:`Response` you have to use the `direct_passthrough` mode. :param file: a :class:`file`-like object with a :meth:`~file.read` method. :param buffer_size: number of bytes for one iteration.
