Subclasses only need to override get_entry_weight()
to return the
right weight for a given entry.
This class also delays committing any changes until the user moves to the next or previous song. So if the user changes the entry-view to contain different songs, but changes it back before the current song finishes, they will not see any changes to their history of played songs.
struct RBRandomPlayOrderClass { RBPlayOrderClass parent_class; /** * get_entry_weight: * @rorder: the play order * @db: the #RhythmDB * @entry: the #RhythmDBEntry to weight * * This method should return a weight for the given @entry. * * Return value: weighting for @entry */ double (*get_entry_weight) (RBRandomPlayOrder *rorder, RhythmDB *db, RhythmDBEntry *entry); };
