Interface MetadataCacheCreationListener

public interface MetadataCacheCreationListener

The listener interface for receiving updates on the progress of creating a metadata cache file.

Classes that are interested in displaying a progress bar during the (potentially lengthy) process, and allowing the user to cancel it, can implement this interface.

The listener object created from that class is then passed to MetadataFinder.createMetadataCache(SlotReference, int, File, MetadataCacheCreationListener) in order to be able to display progress during the process of creating the cache file. As each track is added to the cache, cacheCreationContinuing(TrackMetadata, int, int) is called, with the most recent track added, the number of tracks that have been added so far, and the total that need to be added. If it returns false, the creation of the cache file will be canceled.
