 A disk-based implementation of the FileItem interface. This implementation retains smaller items in memory, while writing larger ones to disk. The threshold between these two is configurable, as is the location of files that are written to disk. 

   
 In typical usage, an instance of DiskFileItemFactory would be created, configured, and then passed to a FileUpload implementation such as ServletFileUpload. 

   

     The following code fragment demonstrates this usage.
   


       DiskFileItemFactory factory = new DiskFileItemFactory();
       // maximum size that will be stored in memory
       factory.setSizeThreshold(4096);
       // the location for saving data that is larger than getSizeThreshold()
       factory.setRepository(new File("/tmp"));
       ServletFileUpload upload = new ServletFileUpload(factory);


   

     Please see the FileUpload
     User Guide
     for further details and examples of how to use this package.
