Interface GroupManager

public interface GroupManager

Describes the service interface for managing groups.

Group hierarchy elements are being returned as a Groupcollection. The backing implementation must appropriately map the group hierarchy to a preferences sub-tree.

The convention {principal}.{subprincipal} has been chosen to name groups hierachies. Implementation follow the conventions enforced by the Preferences API.
