public interface FileItemStream
This interface provides access to a file or form item that was received within a
multipart/form-data POST request. The items contents are retrieved by calling
openStream().
Instances of this class are created by accessing the iterator, returned by
FileUploadBase.getItemIterator(RequestContext).
Note: There is an interaction between the iterator and its associated instances of
FileItemStream: By invoking Iterator.hasNext() on the iterator, you
discard all data, which hasn't been read so far from the previous data.
