Interface MultipartHttpServletRequest

All Superinterfaces:: HttpServletRequest, ServletRequest

All Known Implementing Classes:: AbstractMultipartHttpServletRequest, CosMultipartHttpServletRequest, DefaultMultipartHttpServletRequest

public interface MultipartHttpServletRequest
extends HttpServletRequest
extends HttpServletRequest

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

A concrete implementation is DefaultMultipartHttpServletRequest. As an intermediate step, AbstractMultipartHttpServletRequest can be subclassed.
