• .new(operation : Type, filter : BER)

Class Method Summary

• .approx(object : String, value, escaped : Bool = false)

  approxMatch [8] — like an equality assertion, but the server applies its approximate-matching rule for the attribute (RFC 4511 §4.5.1.7.6).

• .begins(attribute : String, value)
• .conjoin(left : BER, right : BER)

  Logical AND [0] of two filters (see also #&).

• .conjoin(left : Filter, right : Filter)

  Logical AND [0] of two filters (see also #&).

• .contains(attribute : String, value)
• .disjoin(left : BER, right : BER)

  Logical OR [1] of two filters (see also #|).

• .disjoin(left : Filter, right : Filter)

  Logical OR [1] of two filters (see also #|).

• .ends(attribute : String, value)
• .equal(object : String, value, escaped : Bool = false)
• .escape(string : String) : String

  Escape a string for use in an LDAP filter

• .extensible(value, *, attribute : String | Nil = nil, rule : String | Nil = nil, dn_attributes : Bool = false)

  extensibleMatch [9] MatchingRuleAssertion (RFC 4511 §4.5.1.7.7): { matchingRule [1] OPT, type [2] OPT, matchValue [3], dnAttributes [4] BOOLEAN DEFAULT FALSE } At least one of attribute (type) or rule (matchingRule) must be present.

• .greater_than(object : String, value)
• .less_than(object : String, value)
• .negate(filter : Filter)
• .negate(filter : BER)
• .not_equal(object : String, value, escaped : Bool = false)
• .present?(attribute : String)
• .unescape(value : String, escaped : Bool = false) : String

Instance Method Summary

• #&(other)

  Joins two or more filters so that all conditions must be true.

• #|(other)

  Selects entries where either the left or right side are true.

• #~

  Negates a filter.

• #operation : Type
• #to_ber : ASN1::BER
