Class Overview

Abstract superclass for RSS Feed views, using java.net's ROME package.

Application-specific view classes will extend this class. The view will be held in the subclass itself, not in a template.

Main entry points are the buildFeedMetadata(Map, WireFeed, HttpServletRequest) and buildFeedItems(Map, HttpServletRequest, HttpServletResponse).

Thanks to Jettro Coenradie and Sergio Bossa for the original feed view prototype!

Protected Methods

protected final void buildFeedEntries (Map<String, Object> model, Channel channel, HttpServletRequest request, HttpServletResponse response)

Invokes buildFeedItems(Map, HttpServletRequest, HttpServletResponse) to get a list of feed items.

Parameters

model	the model Map
channel	the feed to add entries to
request	in case we need locale etc. Shouldn't look at attributes.
response	in case we need to set cookies. Shouldn't write to it.

Throws

Exception

protected abstract List<Item> buildFeedItems (Map<String, Object> model, HttpServletRequest request, HttpServletResponse response)

Subclasses must implement this method to build feed items, given the model.

Note that the passed-in HTTP response is just supposed to be used for setting cookies or other HTTP headers. The built feed itself will automatically get written to the response after this method returns.

Parameters

model	the model Map
request	in case we need locale etc. Shouldn't look at attributes.
response	in case we need to set cookies. Shouldn't write to it.

Returns

the feed items to be added to the feed

Throws

Exception	any exception that occured during document building

protected Channel newFeed ()

Create a new Channel instance to hold the entries.

By default returns an RSS 2.0 channel, but the subclass can specify any channel.

Returns

the newly created Feed instance
