NAME
    Net::LDAP::Control::Paged - LDAPv3 Paged results control object

SYNOPSIS
     use Net::LDAP;
     use Net::LDAP::Control::Paged;
     use Net::LDAP::Constant qw( LDAP_CONTROL_PAGED );

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

     $page = Net::LDAP::Control::Paged->new( size => 100 );

     @args = ( base     => "cn=subnets,cn=sites,cn=configuration,$BASE_DN",
               scope    => "subtree",
               filter   => "(objectClass=subnet)",
               callback => \&process_entry, # Call this sub for each entry
               control  => [ $page ],
     );

     my $cookie;
     while (1) {
       # Perform search
       my $mesg = $ldap->search( @args );

       # Only continue on LDAP_SUCCESS
       $mesg->code  and last;

       # Get cookie from paged control
       my($resp)  = $mesg->control( LDAP_CONTROL_PAGED )  or last;
       $cookie    = $resp->cookie;

       # Only continue if cookie is nonempty (= we're not done)
       last  if (!defined($cookie) || !length($cookie));

       # Set cookie in paged control
       $page->cookie($cookie);
     }

     if (defined($cookie) && length($cookie)) {
       # We had an abnormal exit, so let the server know we do not want any more
       $page->cookie($cookie);
       $page->size(0);
       $ldap->search( @args );
     }

DESCRIPTION
    "Net::LDAP::Control::Paged" provides an interface for the creation and
    manipulation of objects that represent the "pagedResultsControl" as
    described by RFC 2696.

    The control is allowed on LDAP search requests ("search" in Net::LDAP)
    only. On other operations it will - depending on the value of the
    parameter "critical" - either be ignored or lead to errors.

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

    cookie
        The value to use as the cookie. This is not normally set when an
        object is created, but is set from the cookie value returned by the
        server. This associates a search with a previous search, so the
        server knows to return the page of entries following the entries it
        returned the previous time.

    size
        The page size that is required. This is the maximum number of
        entries that the server will return to the search request.

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.
