Class Group

java.lang.Object
  com.antelmann.cddb.Resource
      com.antelmann.cddb.Group

All Implemented Interfaces:

Serializable, Comparable<Resource>

public class Group
extends Resource

Group is a resource made up by multiple individual resources; this could be an artist, a band, an orchestra, a chorus or anything similar - including yet another group.

Though normally a group would normally contain Artists rather than plain Resources, it is conceivable that a group also just contains Resource objects (let's say an orchestra or group is famous for using a specific instrument or something similar).
