Class SortResponseControl

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

Constructors

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.

Methods

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.
