All Implemented Interfaces:

java.lang.Runnable

public class UpdateFeeds

extends AbstractSwingWorker

Load all items in a given channel or load all feeds in a mixed list of channels and items.

Note: This thread is used by the TreeView to update feeds. The TreeView consists of folders which are received here as Channels. The leaves or Items in the TreeView are the actual channels to be downloaded and displayed in the HtmlView.

Either the list is given a value or the channel is given a value; but not both. If both are set, only the channel will be seen.
