Class PagedResultsResponseControl

All Implemented Interfaces:
Serializable, Control 
public final class PagedResultsResponseControl
extends BasicControl

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
     }
Since:
1.5

PagedResultsResponseControl

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

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.

Methods

getResultSize

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.

getCookie

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.
