/**
 * This class is a placeholder for form values.  In a multipart request, files are represented by
 * set and get methods that use the class org.apache.struts.upload.FormFile, an interface with
 * basic methods to retrieve file information.  The actual structure of the FormFile is dependant
 * on the underlying impelementation of multipart request handling.  The default implementation
 * that struts uses is org.apache.struts.upload.DiskMultipartRequestHandler.
