It is one of the following values (which represent the LDAP operations indicated next to them): =over 4 =item 1 = add =item 2 = delete =item 4 = modify =item 8 = modDN =back =item previousDN When changeType is 8 (for modDN) this parameter tells the entry's DN before the modDN operation. In all other cases this value is not defined. =item changeNumber This is the change number according to assigned by a server for the change. If a server supports an LDAP Change Log it should include this field. =back Usually you do not need to create a C control yourself because it is provided by the server in response to an option with the C control. =head1 METHODS As with L each constructor argument described above is also available as a method on the object which will return the current value for the attribute if called without an argument, and set a new value for the attribute if called with an argument. =head1 SEE ALSO L, L, L =head1 AUTHOR Peter Marschall Epeter@adpm.deE, based on Net::LDAP::Control::Page from Graham Barr Egbarr@pobox.comE and the preparatory work of Don Miller Edonm@uidaho.eduE.
