Net::LDAP::Filter - representation of LDAP filters
use Net::LDAP::Filter;
$filter = Net::LDAP::Filter->new( $filter_str );The Net::LDAP::Filter object lets you directly manipulate LDAP filters without worrying about the string representation and all the associated escaping mechanisms.
- new ( FILTER )
-
Create a new object and parse FILTER.
- 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.
Below is the syntax for a filter given in RFC-2254 http://www.ietf.org/rfc/rfc2254.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 4.1.5 of RFC-2251
matchingrule = MatchingRuleId from Section 4.1.9 of RFC-2251
value = AttributeValue from Section 4.1.6 of RFC-2251
