Class PortletFileUpload
java.lang.Object
org.apache.commons.fileupload.FileUploadBase
org.apache.commons.fileupload.FileUpload
org.apache.commons.fileupload.portlet.PortletFileUpload
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(javax.servlet.http.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.
