Class Group

java.lang.Object
  org.jivesoftware.openfire.group.Group

All Implemented Interfaces:

Externalizable, Serializable, Cacheable

public class Group
extends Object
implements Cacheable, Externalizable

Groups organize users into a single entity for easier management.

The actual group implementation is controlled by the GroupProvider, which includes things like the group name, the members, and adminstrators. Each group also has properties, which are always stored in the Openfire database.
