/*#
@method open Uploaded
@brief Opens a read-only Falcon Stream pointing to the uploaed file.
@return A Falcon stream.
@raise IoError on open or write error.
@raise TypeError if the storage property is not a valid filename.
If @b data is filled, this method creates a memory
read-only StringStream accessing the data as a file. If it was
stored in a temporary file named as reported by the @b storage
property, that file is open in read-only/shared mode.
This method allows to obtain a valid readable stream no matter if the
uploaded file was cached in memory or temporarily stored to disk.
