FileUploadBase (The Adobe AEM Quickstart and Web Application.)

java.lang.Object
- org.apache.commons.fileupload.FileUploadBase

Direct Known Subclasses:

DiskFileUpload, FileUpload
```
public abstract class FileUploadBase
extends java.lang.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.

```
public static final boolean isMultipartContent(RequestContext ctx)
```
    Utility method that determines whether the request contains multipart content.
