public class LdapSortResponseControl
extends LDAPSortControl
implements Control
The LDAP server sends back a sort response control to indicate
the result of the sorting operation. (The OID for this control
is 1.2.840.113556.1.4.474.)
This control contains:
- the result code from the sorting operation
- optionally, the first attribute type in the sort key list
that resulted in an error (for example, if the attribute does
not exist)
To parse this control, use the
parseResponse
method.
The following table lists what kinds of results to expect from the
LDAP server under different situations:
Does the Server Support the Sorting Control? | Is the Sorting Control Marked As Critical? | Other Conditions | Results from LDAP Server |
---|

|
Yes
|
None
|
- The server does not send back any entries.
- An LDAPException.UNAVAILABLE_CRITICAL_EXTENSION
exception is thrown.

byte[] | getEncodedValue() - Retrieves the ASN.1 BER encoded value of the LDAP control.
|
String | getFailedAttribute() - Get the first attribute type from the sort key list that
resulted in an error
|
int | getResultCode() - Return the sort result code
|
NamingException | getSortException() - Return corresponding NamingException for the sort error code

getEncodedValue
public byte[] getEncodedValue()
Retrieves the ASN.1 BER encoded value of the LDAP control.
Null is returned if the value is absent.
- A possibly null byte array representing the ASN.1 BER
encoded value of the LDAP control.
getFailedAttribute
public String getFailedAttribute()
Get the first attribute type from the sort key list that
resulted in an error
- Attribute name that resulted in an error
getResultCode
public int getResultCode()
Return the sort result code
getSortException
public NamingException getSortException()
Return corresponding NamingException for the sort error code
- NamingException for the sort error code
