All Implemented Interfaces:

Agent, CollectionHandler, Good, MetagluePrimitives, Remote, Serializable, Spy

Direct Known Subclasses:

SongListHandlerAgent

public class CollectionHandlerAgent

extends GoodAgent

implements CollectionHandler

This class is a unification of the existing DiscChangerHandler and Mp3CollectionHandler agents to deal with a unified Collection (which could contain Mp3s, CDs, or whatever we like) We should probably place the SQL stuff elsewhere, maybe letting the individual SongContainers decide what to put where. But that's a major rewrite for another day.
