Adds an owner. Owners can modify ACL contents and can disassociate ACLs from the objects they protect in the AclConfig interface. The caller principal must be a part of the owners list of the ACL in order to invoke this method. The initial owner is configured at ACL construction time.

Parameters:

caller - the principal who is invoking this method.

owner - The owner that should be added to the owners list.

Returns:

true if success, false if already an owner.

Throws: NotOwnerException

if the caller principal is not on the owners list of the Acl.

 public synchronized boolean deleteOwner(Principal caller,
                                         Principal owner) throws NotOwnerException, LastOwnerException

Delete owner. If this is the last owner in the ACL, an exception is raised. The caller principal must be a part of the owners list of the ACL in order to invoke this method.

Parameters:

caller - the principal who is invoking this method.

owner - The owner to be removed from the owners list.

Returns:

true if the owner is removed, false if the owner is not part of the owners list.

Throws: NotOwnerException

if the caller principal is not on the owners list of the Acl.

if there is only one owner left in the group, then deleteOwner would leave the ACL owner-less. This exception is raised in such a case.
