NAME
    Net::LDAP::Control::EntryChange - LDAPv3 Entry Change Notification control object

SYNOPSIS
     use Net::LDAP;
     use Net::LDAP::Control::PersistentSearch;
     use Net::LDAP::Constant qw(LDAP_CONTROL_ENTRYCHANGE);

     $ldap = Net::LDAP->new( "ldap.mydomain.eg" );

     $persist = Net::LDAP::Control::PersistentSearch->new( changeTypes => 15,
                                                           changesOnly => 1,
                                                           returnECs => 1 );

     $srch = $ldap->search( base     => "cn=People,dc=mydomain,dc=eg",
                            filter   => "(objectClass=person)",
                            callback => \&process_entry, # call for each entry
                            control  => [ $persist ] );

     die "error: ",$srch->code(),": ",$srch->error()  if ($srch->code());

     sub process_entry {
       my $message = shift;
       my $entry = shift;
       my ($control) = $message->control(LDAP_CONTROL_ENTRYCHANGE);

       print $control->changeType()."\t".$entry->dn()."\n";
     }

DESCRIPTION
    "Net::LDAP::Control::EntryChange" provides an interface for the creation and manipulation of
    objects that represent the "EntryChangeNotification" control as described by
    draft-smith-psearch-ldap-03.txt.

CONSTRUCTOR ARGUMENTS
    In addition to the constructor arguments described in Net::LDAP::Control the following are
    provided.

    changeType
        An integer value telling the type of LDAP operation that the entry has undergone. It is one
        of the following values (which represent the LDAP operations indicated next to them):

        1 = add
        2 = delete
        4 = modify
        8 = modDN

    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.

    changeNumber
        This is the change number according to <draft-good-ldap-changelog-03.txt> assigned by a
        server for the change. If a server supports an LDAP Change Log it should include this field.

    Usually you do not need to create a "Net::LDAP::Control::EntryChange" control yourself because
    it is provided by the server in response to an option with the
    "Net::LDAP::Control::PersistentSearch" control.

METHODS
    As with Net::LDAP::Control 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.
