Interface MultipartActionRequest

All Superinterfaces:: ActionRequest, PortletRequest

All Known Implementing Classes:: DefaultMultipartActionRequest, MockMultipartActionRequest

public interface MultipartActionRequest
extends ActionRequest
extends ActionRequest

Interface which provides additional methods for dealing with multipart content within a portlet request, allowing to access uploaded files. Implementations also need to override the standard ActionRequest methods for parameter access, making multipart parameters available.

A concrete implementation is DefaultMultipartActionRequest.
