Interface Owner

Known Subinterfaces:
Acl

public interface Owner

This interface provides a mechanism for maintaining a list of owners of an access control list (ACL). Since a Principal must be an owner in order to modify the owner list, a mechanism must be provided to specify the initial owner of the ACL. The proper way to do this is for the implementing class to specify the initial owner in the contructor for that class.
