FileUploadBase (Apache Tomcat 8.0.15 API Documentation)

java.lang.Object
- org.apache.tomcat.util.http.fileupload.FileUploadBase

Direct Known Subclasses:

FileUpload
```
public abstract class FileUploadBase
extends Object
```
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 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.
