Method Detail

update

public static void update(java.util.Collection<Feed> feeds,
                          DataSource source)
                   throws UnsupportedRSSFormatException,
                          java.io.IOException

Calling this method will force the RSSUpdater to update all specified feeds using the given DataSource. NOTE: The RSSUpdater updates the feeds sequentially, so if one feed takes a long time to update, feeds after it will remain unparsed for an unspecified amount of time. Do not make calls expecting updating to be immediate. To be notified of completed update of a feed, listen to the given DataSource for a DataEvent.

Parameters:

feeds - Feeds to update

source - DataSouce to use for storing updated information

Throws:

UnsupportedRSSFormatException - Thrown if the RSS file is unsupported by the parser

java.io.IOException - Thrown if unable to connect to the Feed URL (usually indicates a bad URL or no connection to the Internet).
