public class LDAPMatchingRuleUseSchema extends LDAPAttributeSchema
The definition of a matching rule use in the schema. RFC 2252, Lightweight Directory Access Protocol (v3): Attribute Syntax Definitions covers the types of information that need to be specified in the definition of a matching rule use. According to the RFC, the description of a matching rule use can include the following information:

  • an OID identifying the matching rule
  • a name identifying the matching rule use
  • a description of the matching rule use
  • a list of attributes the matching rule applies to

When you construct an LDAPMatchingRuleUseSchema object, you can specify these types of information as arguments to the constructor or in the MatchingRuleUseDescription format specified in RFC 2252. When an LDAP client searches an LDAP server for the schema, the server returns schema information as an object with values in this format.

You can get the name, OID, and description of this matching rule use definition by using the getName, getOID, and getDescription methods inherited from the abstract class LDAPSchemaElement. Custom qualifiers are accessed with getQualifier and getQualifierNames from LDAPSchemaElement.

To add or remove this matching rule definition from the schema, use the add and remove methods, which this class inherits from the LDAPSchemaElement abstract class.

RFC 2252 defines MatchingRuleUseDescription follows: 

Values of the matchingRuleUse list the attributes which are suitable
for use with an extensible matching rule.

   MatchingRuleUseDescription = "(" whsp
       numericoid whsp  ; MatchingRule identifier
       [ "NAME" qdescrs ]
       [ "DESC" qdstring ]
       [ "OBSOLETE" ]
      "APPLIES" oids    ; AttributeType identifiers
   whsp ")"

    • LDAPMatchingRuleUseSchema

      public LDAPMatchingRuleUseSchema(String name, String oid, String description, String[] attributes)
      Constructs a matching rule use definition, using the specified information.
      Parameters:
      name - name of the matching rule
      oid - object identifier (OID) of the matching rule in dotted-decimal format (for example, "1.2.3.4")
      description - description of the matching rule
      attributes - array of the OIDs of the attributes for which the matching rule is applicable

    • LDAPMatchingRuleUseSchema

      public LDAPMatchingRuleUseSchema(String use)
      Constructs a matching rule use definition based on descriptions in the MatchingRuleUseDescription format. For information on this format, (see RFC 2252, Lightweight Directory Access Protocol (v3): Attribute Syntax Definitions. This is the format that LDAP servers and clients use to exchange schema information. For example, when you search an LDAP server for its schema, the server returns an entry with attributes that include "matchingrule" and "matchingruleuse". The values of these attributes are matching rule descriptions in this format.

      Parameters:
      use - definition of the use of the matching rule in the MatchingRuleUseDescription format

  • Method Details

    • getApplicableAttributes

      public String[] getApplicableAttributes()
      Gets the list of the OIDs of the attribute types which can be used with the matching rule.
      Returns:
      array of the OIDs of the attribute types which can be used with the matching rule.

    • getValue

      public String getValue()
      Gets the matching rule use definition in the string representation of the MatchingRuleUseDescription data type defined in X.501 (see RFC 2252, Lightweight Directory Access Protocol (v3): Attribute Syntax Definitions for a description of these formats). This is the format that LDAP servers and clients use to exchange schema information. (For example, when you search an LDAP server for its schema, the server returns an entry with the attributes "matchingrules" and "matchingruleuse". The values of these attributes are matching rule description and matching rule use description in these formats.)

      Overrides:
      getValue in class LDAPSchemaElement
      Returns:
      a string in a format that can be used as the value of the matchingruleuse attribute (which describes the use of a matching rule in the schema) of a subschema object

    • toString

      public String toString()
      Gets the definition of the matching rule use in a user friendly format. This is the format that the matching rule use definition uses when you print the matching rule or the schema.
      Overrides:
      toString in class LDAPAttributeSchema
      Returns:
      definition of the matching rule in a user friendly format.
