Net::LDAP::Filter(3)                 User Contributed Perl Documentation                Net::LDAP::Filter(3)



NAME
       Net::LDAP::Filter - representation of LDAP filters

SYNOPSIS
         use Net::LDAP::Filter;

         $filter = Net::LDAP::Filter->new( $filter_str );

DESCRIPTION
       The Net::LDAP::Filter object lets you directly manipulate LDAP filters without worrying about the
       string representation and all the associated escaping mechanisms.

CONSTRUCTOR
       new ( FILTER )
           Create a new object and parse FILTER.

METHODS
       parse ( FILTER )
           Parse FILTER. The next call to ber will return this filter encoded.

       as_string
           Return the filter in text form.

       print ( [ FH ] )
           Print the text representation of the filter to FH, or the currently selected output handle if FH
           is not given.

FILTER SYNTAX
       Below is the syntax for a filter given in RFC 4515 http://www.ietf.org/rfc/rfc4515.txt

        filter       = "(" filtercomp ")"
        filtercomp   = and / or / not / item
        and          = "&" filterlist
        or           = "|" filterlist
        not          = "!" filter
        filterlist   = 1*filter
        item         = simple / present / substring / extensible
        simple       = attr filtertype value
        filtertype   = equal / approx / greater / less
        equal        = "="
        approx       = "~="
        greater      = ">="
        less         = "<="
        extensible   = attr [":dn"] [":" matchingrule] ":=" value
                       / [":dn"] ":" matchingrule ":=" value
        present      = attr "=*"
        substring    = attr "=" [initial] any [final]
        initial      = value
        any          = "*" *(value "*")
        final        = value
        attr         = AttributeDescription from Section 4.1.4 of RFC 4511
        matchingrule = MatchingRuleId from Section 4.1.8 of RFC 4511
        value        = AttributeValue from Section 4.1.5 of RFC 4511
