| /** |
| * A request/response control used to implement a simple paging of search |
| * results. This is an implementation of RFC 2696 : |
| * <a href="http://www.faqs.org/rfcs/rfc2696.html">LDAP Control Extension for Simple Paged Results Manipulation</a> |
| * <br> |
| * <pre> |
| * This control is included in the searchRequest and searchResultDone |
| * messages as part of the controls field of the LDAPMessage, as defined |
| * in Section 4.1.12 of [LDAPv3]. The structure of this control is as |
| * follows: |
| * |
| * pagedResultsControl ::= SEQUENCE { |
| * controlType 1.2.840.113556.1.4.319, |
| * criticality BOOLEAN DEFAULT FALSE, |
| * controlValue searchControlValue |
| * } |
| * |
| * The searchControlValue is an OCTET STRING wrapping the BER-encoded |
| * version of the following SEQUENCE: |
| * |
| * realSearchControlValue ::= SEQUENCE { |
| * size INTEGER (0..maxInt), |
| * -- requested page size from client |
| * -- result set size estimate from server |
| * cookie OCTET STRING |
| * } |
| * |
| * </pre> |
