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.
    
    NOTE:This method will be moved to the ServletFileUpload class after the FileUpload 1.1 release. Unfortunately, since this method is static, it is not possible to provide its replacement until this method is removed.

    Returns:
    
    true if the request is multipart; false otherwise.

    Parameters:
    
    req - The servlet request to be evaluated. Must be non-null.
