public interface EntryChange
extends Control

A response control that may be returned by Persistent Search entry responses. It contains addition change information to describe the exact change that occurred to an entry. The exact details of this control are covered in section 5 of this (yes) expired draft: Persistent Search Draft v03 which is printed out below for convenience:

    5.  Entry Change Notification Control

    This control provides additional information about the change the caused
    a particular entry to be returned as the result of a persistent search.
    The controlType is "2.16.840.1.113730.3.4.7".  If the client set the
    returnECs boolean to TRUE in the PersistentSearch control, servers MUST
    include an EntryChangeNotification control in the Controls portion of
    each SearchResultEntry that is returned due to an entry being added,
    deleted, or modified.

               EntryChangeNotification ::= SEQUENCE
               {
                         changeType ENUMERATED
                         {
                                 add             (1),
                                 delete          (2),
                                 modify          (4),
                                 modDN           (8)
                         },
                         previousDN   LDAPDN OPTIONAL,     -- modifyDN ops. only
                         changeNumber INTEGER OPTIONAL     -- if supported
               }

    changeType indicates what LDAP operation caused the entry to be
    returned.

    previousDN is present only for modifyDN operations and gives the Dn of
    the entry before it was renamed and/or moved.  Servers MUST include this
    optional field only when returning change notifications as a result of
    modifyDN operations.

    changeNumber is the change number [CHANGELOG] assigned by a server for
    the change.  If a server supports an LDAP Change Log it SHOULD include
    this field.
