Interface semper.preferences.PrefGroupToAdd

public interface PrefGroupToAdd
extends Object
This interface must be implemented by all manager who want to add preferences groups but are initialised before the Preferences manager. For instance when the ACM is initialised, some standard roles are created. Some of them need a password to be unlocked. These must be modifiable by the user through its preferences. So the ACM at initialisation uses an implementation of this interface in order to build its preferences groups prior the moment these groups will be added to the preferences manager. This interface contains only three functions (methods with output value and only relevent through this output value): the build() function returns the new group to be added, wichSubGroup() which tell in which subgroup the new group must be added and getName() which returns the name of the group to be added.
