UploadedFiles(ExternalContext externalContext) 
{
    externalContext.getRequestMap().put(_UPLOADED_FILES_KEY, this);
    _map = new HashMap< String, UploadedFile >();
}

Creates an UploadedFiles.

  void __put(String name,
    UploadedFile file) 
{
    _map.put(name, file);
}

Store a single UploadedFile.

 public  void dispose() 
{
    Iterator< UploadedFile > iterator = _map.values().iterator();
    while (iterator.hasNext())
    {
      UploadedFile file = iterator.next();
      file.dispose();
    }
    _map.clear();
    _totalMemory    = 0;
    _totalDiskSpace = 0;
}

Dispose of all UploadedFiles. This will happen automatically when the current request ends, so clients do not need to call this method. However, if a developer is finished with processing files, this will free up resources earlier.

 public long getTotalDiskSpace() 
{
    return _totalDiskSpace;
}

Return the tally of total disk space used.

 public long getTotalMemory() 
{
    return _totalMemory;
}

Return the tally of total memory used.

 public UploadedFile getUploadedFile(String name) 
{
    UploadedFile file = _map.get(name);
    if (file == null)
      return null;
    return new FixFilename(file, _characterEncoding);
}

Returns a single uploaded file.

{
    Map< String, Object > requestMap =
      context.getExternalContext().getRequestMap();
    return (UploadedFiles) requestMap.get(_UPLOADED_FILES_KEY);
}

Returns the map of uploaded files for the current request.

 public Iterator getUploadedNames() 
{
    return _map.keySet().iterator();
}

Returns an Iterator of the names of all uploaded files.

    String encoding) 
{
    UploadedFiles files = (UploadedFiles)
      externalContext.getRequestMap().get(_UPLOADED_FILES_KEY);
    _setCharacterEncoding(files, encoding);
}

Store the character encoding for the current request.

 public static  void setCharacterEncoding(HttpServletRequest req,
    String encoding) 
{
    UploadedFiles files = (UploadedFiles)
      req.getAttribute(_UPLOADED_FILES_KEY);
    _setCharacterEncoding(files, encoding);
}

{
