public class RestletFileUpload
extends FileUpload

High level API for processing file uploads. This class handles multiple files per single HTML widget, sent using the "multipart/mixed" encoding type, as specified by RFC 1867. Use parseRequest(Request) method 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.

In addition, it is possible to use FileUploadBase.getItemIterator(org.apache.commons.fileupload.RequestContext) method.

Method Detail

getItemIterator

public FileItemIterator getItemIterator(Representation multipartForm)
                                 throws FileUploadException,
                                        IOException

Processes an RFC 1867 compliant multipart/form-data input representation. Note that this will not result in the writing of the parts on the disk but will instead allow you to use stream access.

Parameters:

multipartForm - The input representation.

Returns:

An iterator to instances of FileItemStream parsed from the request.

Throws:

FileUploadException

IOException

parseRepresentation

public List<FileItem> parseRepresentation(Representation multipartForm)
                                   throws FileUploadException

Processes an RFC 1867 compliant multipart/form-data input representation. Note that this will result in the writing of the parts on the disk.

Parameters:

multipartForm - The multipart representation to be parsed.

Returns:

A list of FileItem instances parsed, in the order that they were transmitted.

Throws:

FileUploadException - if there are problems reading/parsing the request or storing files.

parseRequest

public List<FileItem> parseRequest(Request request)
                            throws FileUploadException

Processes an RFC 1867 compliant multipart/form-data input representation. Note that this will result in the writing of the parts on the disk.

Parameters:

request - The request containing the entity to be parsed.

Returns:

A list of FileItem instances parsed, in the order that they were transmitted.

Throws:

FileUploadException - if there are problems reading/parsing the request or storing files.
