public final Class PagedResultsResponseControl

extends BasicControl
Class Inheritance
Imports
java.io.IOException, com.sun.jndi.ldap.Ber, .BerDecoder
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
    }
