public class GroupUpload
extends Upload

The GroupUpload class wraps a reference to a file that has been uploaded to a group file exchange in a course. This object only represents the information in the database used to track the file reference. References to the actual file system objects must be obtained separately.

Note that GroupUpload objects are only meant to deal with files associated with the group file exchange. It does not deal with files in other contexts, such as content uploads or the course drop box.
