Example 1 with FeedListUpdateEvent

use of de.danoeh.antennapod.event.FeedListUpdateEvent in project AntennaPod by AntennaPod.

the class DBTasks method updateFeed.

/**
 * Adds new Feeds to the database or updates the old versions if they already exists. If another Feed with the same
 * identifying value already exists, this method will add new FeedItems from the new Feed to the existing Feed.
 * These FeedItems will be marked as unread with the exception of the most recent FeedItem.
 * <p/>
 * This method can update multiple feeds at once. Submitting a feed twice in the same method call can result in undefined behavior.
 * <p/>
 * This method should NOT be executed on the GUI thread.
 *
 * @param context Used for accessing the DB.
 * @param newFeed The new Feed object.
 * @param removeUnlistedItems The item list in the new Feed object is considered to be exhaustive.
 *                            I.e. items are removed from the database if they are not in this item list.
 * @return The updated Feed from the database if it already existed, or the new Feed from the parameters otherwise.
