package org.apache.tomcat.util.http.fileupload;

High level API for processing file uploads.
This class handles multiple files per single HTML widget, sent using multipart/mixed encoding type, as specified by RFC 1867. Use FileUploadBase.parseRequest(RequestContext) to acquire a list of FileItems associated with a given HTML widget.
How the data for individual parts is stored is determined by the factory
used to create them; a given part may be in memory, on disk, or somewhere
else.
