PortletFileUpload

public class PortletFileUpload extends FileUpload (Code)

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 PortletFileUpload.parseRequest(javax.servlet.http.HttpServletRequest) to acquire a list of org.apache.commons.fileupload.FileItem 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 Summary
public	PortletFileUpload() Constructs an uninitialised instance of this class.
public	PortletFileUpload(FileItemFactory fileItemFactory) Constructs an instance of this class which uses the supplied factory to create `FileItem` instances.

Method Summary
public FileItemIterator	getItemIterator(ActionRequest request) Processes an RFC 1867 compliant `multipart/form-data` stream. Parameters: request - The portlet request to be parsed.
final public static boolean	isMultipartContent(ActionRequest request) Utility method that determines whether the request contains multipart content. Parameters: request - The portlet request to be evaluated.
public List	parseRequest(ActionRequest request) Processes an RFC 1867 compliant `multipart/form-data` stream. Parameters: request - The portlet request to be parsed.

Constructor Detail

PortletFileUpload
public PortletFileUpload()(Code)
	Constructs an uninitialised instance of this class. A factory must be configured, using `setFileItemFactory()`, before attempting to parse requests. See Also: FileUpload.FileUpload(FileItemFactory)

PortletFileUpload
public PortletFileUpload(FileItemFactory fileItemFactory)(Code)
	Constructs an instance of this class which uses the supplied factory to create `FileItem` instances. See Also: FileUpload.FileUpload Parameters: fileItemFactory - The factory to use for creating file items.

Method Detail

getItemIterator
public FileItemIterator getItemIterator(ActionRequest request) throws FileUploadException, IOException(Code)
	Processes an RFC 1867 compliant `multipart/form-data` stream. Parameters: request - The portlet request to be parsed. An iterator to instances of `FileItemStream`parsed from the request, in the order that they weretransmitted. throws: FileUploadException - if there are problems reading/parsingthe request or storing files. throws: IOException - An I/O error occurred. This may be a networkerror while communicating with the client or a problem whilestoring the uploaded content.

isMultipartContent
final public static boolean isMultipartContent(ActionRequest request)(Code)
	Utility method that determines whether the request contains multipart content. Parameters: request - The portlet request to be evaluated. Must be non-null. `true` if the request is multipart;`false` otherwise.

parseRequest
public List parseRequest(ActionRequest request) throws FileUploadException(Code)
	Processes an RFC 1867 compliant `multipart/form-data` stream. Parameters: request - The portlet request to be parsed. A list of `FileItem` instances parsed from therequest, in the order that they were transmitted. throws: FileUploadException - if there are problems reading/parsingthe request or storing files.
