NAME
Net::LDAP::Control::Sort - Server Side Sort (SSS) control object
SYNOPSIS
use Net::LDAP::Control::Sort;
use Net::LDAP::Constant qw(LDAP_CONTROL_SORTRESULT);
$sort = Net::LDAP::Control::Sort->new(
order => "cn -phone"
);
$mesg = $ldap->search( @args, control => [ $sort ]);
($resp) = $mesg->control( LDAP_CONTROL_SORTRESULT );
print "Results are sorted\n" if $resp and !$resp->result;
DESCRIPTION
"Net::LDAP::Control::Sort" is a sub-class of
Net::LDAP::Control. It provides a class
for manipulating the
LDAP Server Side Sort (
SSS) request control
1.2.840.113556.1.4.473 as defined in
RFC-2891
If the server supports sorting, then the response from a search
operation will include a sort result control. This control is handled
by Net::LDAP::Control::SortResult.
CONSTRUCTOR ARGUMENTS
- order
-
A string which defines how entries may be sorted. It consists of
multiple directives, separated by whitespace. Each directive describes how
to sort entries using a single attribute. If two entries have identical
attributes, then the next directive in the list is used.
Each directive specifies a sorting order as follows
-attributeType:orderingRule
The leading "-" is optional, and if present indicates that the sorting order should
be reversed. "attributeType" is the attribute name to sort by. "orderingRule" is optional and
indicates the rule to use for the sort and should be valid for the given "attributeType".
Any one attributeType should only appear once in the sorting list.
Examples
"cn" sort by cn using the default ordering rule for the cn attribute
"-cn" sort by cn using the reverse of the default ordering rule
"age cn" sort by age first, then by cn using the default ordering rules
"cn:1.2.3.4" sort by cn using the ordering rule defined as 1.2.3.4
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.
