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 or last;

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

 if ($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.

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 avaliable 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.
