All Implemented Interfaces:

Control, RequestControl, ResponseControl

public class PagedResultsControl
extends AbstractControl
implements RequestControl, ResponseControl

Request/response control for PagedResults. See RFC 2696. Control is defined as:

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