## Class SortResponseControl

- java.lang.Object
- - javax.naming.ldap.BasicControl
  - - javax.naming.ldap.SortResponseControl

- All Implemented Interfaces:
    Serializable, Control

      public final class SortResponseControl
      extends BasicControl

  Indicates whether the requested sort of search results was successful or not. When the result code indicates success then the results have been sorted as requested. Otherwise the sort was unsuccessful and additional details regarding the cause of the error may have been provided by the server.

  The code sample in `SortControl` shows how this class may be used.

  This class implements the LDAPv3 Response Control for server-side sorting as defined in RFC 2891. The control's value has the following ASN.1 definition:

           SortResult ::= SEQUENCE {
              sortResult  ENUMERATED {
                  success                   (0), -- results are sorted
                  operationsError           (1), -- server internal failure
                  timeLimitExceeded         (3), -- timelimit reached before
                                                 -- sorting was completed
                  strongAuthRequired        (8), -- refused to return sorted
                                                 -- results via insecure
                                                 -- protocol
                  adminLimitExceeded       (11), -- too many matching entries
                                                 -- for the server to sort
                  noSuchAttribute          (16), -- unrecognized attribute
                                                 -- type in sort key
                  inappropriateMatching    (18), -- unrecognized or inappro-
                                                 -- priate matching rule in
                                                 -- sort key
                  insufficientAccessRights (50), -- refused to return sorted
                                                 -- results to this client
                  busy                     (51), -- too busy to process
                  unwillingToPerform       (53), -- unable to sort
                  other                    (80)
                  },
            attributeType [0] AttributeType OPTIONAL }

    - #### OID

          public static final String OID

      The server-side sort response control's assigned object identifier is 1.2.840.113556.1.4.474.

  - ### Constructor Detail

    - #### SortResponseControl

          public SortResponseControl(String id,
                             boolean criticality,
                             byte[] value)
                              throws IOException

      Constructs a control to indicate the outcome of a sort request.
      Parameters:
        `id` - The control's object identifier string.
        `criticality` - The control's criticality.
        `value` - The control's ASN.1 BER encoded value. It is not cloned - any changes to value will affect the contents of the control.
      Throws:
        `IOException` - if an error is encountered while decoding the control's value.

  - ### Method Detail

    - #### isSorted

          public boolean isSorted()

      Determines if the search results have been successfully sorted. If an error occurred during sorting a NamingException is thrown.
      Returns:
        true if the search results have been sorted.

    - #### getResultCode

          public int getResultCode()

      Retrieves the LDAP result code of the sort operation.
      Returns:
        The result code. A zero value indicates success.

    - #### getAttributeID

          public String getAttributeID()

      Retrieves the ID of the attribute that caused the sort to fail. Returns null if no ID was returned by the server.
      Returns:
        The possibly null ID of the bad attribute.

    - #### getException

          public NamingException getException()

      Retrieves the NamingException appropriate for the result code.
      Returns:
        A NamingException or null if the result code indicates success.
