PagedResultsResponseControl

extends BasicControl
java.lang.Object
   ↳ javax.naming.ldap.BasicControl
     ↳ javax.naming.ldap.PagedResultsResponseControl

Class Overview

Indicates the end of a batch of search results. Contains an estimate of the total number of entries in the result set and an opaque cookie. The cookie must be supplied to the next search operation in order to get the next batch of results.

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

This class implements the LDAPv3 Response Control for paged-results as defined in RFC 2696. The control's value has the following ASN.1 definition:


     realSearchControlValue ::= SEQUENCE {
         size      INTEGER (0..maxInt),
                           -- requested page size from client
                           -- result set size estimate from server
         cookie    OCTET STRING
     }

Constants

public static final String OID

The paged-results response control's assigned object identifier is 1.2.840.113556.1.4.319.

Constant Value: "1.2.840.113556.1.4.319"

Public Constructors

public PagedResultsResponseControl (String id, boolean criticality, byte[] value)

Constructs a paged-results response control.

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 was encountered while decoding the control's value.

Public Methods

public byte[] getCookie ()

Retrieves the server-generated cookie. Null is returned when there are no more entries for the server to return.

Returns
  • A possibly null server-generated cookie. It is not cloned - any changes to the cookie will update the control's state and thus are not recommended.

public int getResultSize ()

Retrieves (an estimate of) the number of entries in the search result.

Returns
  • The number of entries in the search result, or zero if unknown.
