Examples of com.rometools.rome.io.WireFeedOutput

com.rometools.rome.io.WireFeedOutput
Generates an XML document (String, File, OutputStream, Writer, W3C DOM document or JDOM document) out of an WireFeed (RSS/Atom).
It generates all flavors of RSS (0.90, 0.91, 0.92, 0.93, 0.94, 1.0 and 2.0) and Atom 0.3 feeds. Generators are plugable (they must implement the ModuleParser interface).
