All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, javax.naming.ldap.Control

public class LdapSortResponseControl
extends netscape.ldap.controls.LDAPSortControl
implements javax.naming.ldap.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
No	Yes	None	The server does not send back any entries. An LDAPException.UNAVAILABLE_CRITICAL_EXTENSION exception is thrown.
	No	None	The server ignores the sorting control and returns the entries unsorted.
Yes	Yes	The server cannot sort the results using the specified sort key list.	The server does not send back any entries. An LDAPException.UNAVAILABLE_CRITICAL_EXTENSION exception is thrown. The server sends back the sorting response control, which specifies the result code of the sort attempt and (optionally) the attribute type that caused the error.
	No		The server returns the entries unsorted. The server sends back the sorting response control, which specifies the result code of the sort attempt and (optionally) the attribute type that caused the error.
	N/A (could either be marked as critical or not)	The server successfully sorted the entries.	The server sends back the sorted entries. The server sends back the sorting response control, which specifies the result code of the sort attempt (LDAPException.SUCCESS).
		The search itself failed (for any reason).	The server sends back a result code for the search operation. The server does not send back the sorting response control.

Method Detail

getFailedAttribute

public java.lang.String getFailedAttribute()

Get the first attribute type from the sort key list that resulted in an error

Overrides:

getFailedAttribute in class netscape.ldap.controls.LDAPSortControl

Returns:

Attribute name that resulted in an error

getResultCode

public int getResultCode()

Return the sort result code

Overrides:

getResultCode in class netscape.ldap.controls.LDAPSortControl

Returns:

The sort result code

getSortException

public javax.naming.NamingException getSortException()

Return corresponding NamingException for the sort error code

Returns:

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.

Specified by:

getEncodedValue in interface javax.naming.ldap.Control

Returns:

A possibly null byte array representing the ASN.1 BER encoded value of the LDAP control.
