org.apache.commons.fileupload.disk.DiskFileItem

The default implementation of the {@link org.apache.commons.fileupload.FileItem FileItem} interface.
After retrieving an instance of this class from a {@link org.apache.commons.fileupload.DiskFileUpload DiskFileUpload} instance (see{@link org.apache.commons.fileupload.DiskFileUpload#parseRequest(javax.servlet.http.HttpServletRequest)}), you may either request all contents of file at once using {@link #get()} orrequest an {@link java.io.InputStream InputStream} with{@link #getInputStream()} and process the file without attempting to loadit into memory, which may come handy with large files. @author Rafal Krzewski @author Sean Legassick @author Jason van Zyl @author John McNally @author Martin Cooper @author Sean C.
