public class LDAPDITContentRuleSchema extends LDAPSchemaElement
The definition of a DIT content rule in the schema. RFC 2252, Lightweight Directory Access Protocol (v3): DIT Content Rule Description covers the types of information to specify when defining a DIT content rule. According to the RFC, the description of a DIT content rule can include the following:

  • an OID identifying the attribute type
  • a name identifying the attribute type
  • a description of the attribute type
  • the name of the parent attribute type
  • the syntax used by the attribute (for example, cis or int)
  • an indication of whether the attribute type is single-valued or multi-valued

When you construct an LDAPDITContentRuleSchema object, you can specify these types of information as arguments to the constructor or in the AttributeTypeDescription 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 attribute values in this format.

There are a number of additional optional description fields which are not explicitly accessible through LDAPDITContentRuleSchema, but which can be managed with setQualifier, getQualifier, and getQualifierNames:

  • OBSOLETE

To get the name, OID, and description of this DIT content rule , use the getName, getOID, and getDescription methods inherited from the abstract class LDAPSchemaElement. Optional and custom qualifiers are accessed with getQualifier and getQualifierNames from LDAPSchemaElement.

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

RFC 2252 defines DITContentRuleDescription as follows:

    DITContentRuleDescription = "("
        numericoid   ; Structural ObjectClass identifier
        [ "NAME" qdescrs ]
        [ "DESC" qdstring ]
        [ "OBSOLETE" ]
        [ "AUX" oids ]    ; Auxiliary ObjectClasses
        [ "MUST" oids ]   ; AttributeType identifiers
        [ "MAY" oids ]    ; AttributeType identifiers
        [ "NOT" oids ]    ; AttributeType identifiers
       ")"

    • LDAPDITContentRuleSchema

      public LDAPDITContentRuleSchema(String name, String oid, String description, boolean obsolete, String[] auxiliary, String[] required, String[] optional, String[] precluded)
      Constructs a DIT content rule definition, using the specified information.
      Parameters:
      name - name of the attribute type
      oid - object identifier (OID) of the attribute type in dotted-string format (for example, "1.2.3.4")
      description - description of attribute type
      obsolete - true if the rule is obsolete
      auxiliary - a list of auxiliary object classes allowed for an entry to which this content rule applies. These may either be specified by name or numeric oid.
      required - a list of user attribute types that an entry to which this content rule applies must contain in addition to its normal set of mandatory attributes. These may either be specified by name or numeric oid.
      optional - a list of user attribute types that an entry to which this content rule applies may contain in addition to its normal set of optional attributes. These may either be specified by name or numeric oid.
      precluded - a list consisting of a subset of the optional user attribute types of the structural and auxiliary object classes which are precluded from an entry to which this content rule applies. These may either be specified by name or numeric oid.
    • LDAPDITContentRuleSchema

      public LDAPDITContentRuleSchema(String raw)
      Constructs a DIT content rule definition based on a description in the DITContentRuleDescription format. For information on this format, (see RFC 2252, Lightweight Directory Access Protocol (v3): DIT Content Rule Description. 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 "objectclasses" and "attributetypes". The values of "attributetypes" are attribute type descriptions in this format.)

      Parameters:
      raw - definition of the DIT content rule in the DITContentRuleDescription format
  • Method Details
