Class FeedDaemon

java.lang.Object
  org.apache.jetspeed.daemon.impl.FeedDaemon

All Implemented Interfaces:

Daemon, java.lang.Runnable

public class FeedDaemon

extends java.lang.Object

implements Daemon

A daemon that parses out Jetspeed content sources. It also handles multiple updating Feeds within PortletFactory. When it encounters any RSS feeds that are remote it will pull them locally into the JetspeedDiskCache class via the bulkdownloader class.

The major goals of this Daemon are:

• Parse out OCS feeds
• Put the new Entry into the PortletRegistry
• Get the URL from the Internet if it hasn't been placed in the cache.
• Instantiate the Portlet if it already isn't in the cache.
