Net::LDAP::Control::PersistentSearch - LDAPv3 Persistent Search control object

SYNOPSIS

 use Net::LDAP;
 use Net::LDAP::Control::PersistentSearch;
 $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;
   print $entry->dn()."\n";
   # reduce memory usage
   $message->pop_entry();
 }

DESCRIPTION

"Net::LDAP::Control::PersistentSearch" provides an interface for the creation and manipulation of objects that represent the "PersistentSearch" 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.

changeTypes: An integer value determining the types of changes to look out for. It is the bitwise OR of the following values (which represent the LDAP operations indicated next to them):

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

If it is not given it defaults to 15 meaning all changes.

changesOnly: A Boolean value telling whether the server may return entries that match the search criteria.
If "TRUE" the server must not return any existing entries that match the search criteria. Entries are only returned when they are changed (added, modified, deleted, or subject to a modifyDN operation)
returnECs: If "TRUE", the server must return an Entry Change Notification control with each entry returned as the result of changes.
See Net::LDAP::Control::EntryChange for details.

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.
