Class JakartaServletFileUpload<I extends FileItem<I>,F extends FileItemFactory<I>>

java.lang.Object

org.apache.commons.fileupload2.core.AbstractFileUpload<HttpServletRequest,I,F>

Type Parameters:

I - The FileItem type.

F - the FileItemFactory type.

public class JakartaServletFileUpload<I extends FileItem<I>,F extends FileItemFactory<I>>
extends AbstractFileUpload<HttpServletRequest,I,F>

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(HttpServletRequest) 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.

Constructor Details

JakartaServletFileUpload

public JakartaServletFileUpload()

Constructs an uninitialized instance of this class. A factory must be configured, using setFileItemFactory(), before attempting to parse requests.

JakartaServletFileUpload

public JakartaServletFileUpload(F fileItemFactory)

Constructs an instance of this class which uses the supplied factory to create FileItem instances.

Parameters:

fileItemFactory - The factory to use for creating file items.

See Also:

• AbstractFileUpload()

Method Details

isMultipartContent

public static final boolean isMultipartContent(HttpServletRequest request)

Tests whether the request contains multipart content.

Parameters:

request - The servlet request to be evaluated. Must be non-null.

Returns:

true if the request is multipart; false otherwise.

Specified by:

getItemIterator in class AbstractFileUpload<HttpServletRequest,I extends FileItem<I>,F extends FileItemFactory<I>>

Parameters:

request - The servlet request to be parsed.

Returns:

An iterator to instances of FileItemInput parsed from the request, in the order that they were transmitted.
