056 * This class provides an implementation of the virtual attributes only request
057 * control, which may be included in a search request to indicate that only
058 * virtual attributes should be included in matching entries.
059 * <BR>
060 * <BLOCKQUOTE>
061 *   <B>NOTE:</B>  This class, and other classes within the
062 *   {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
063 *   supported for use against Ping Identity, UnboundID, and
064 *   Nokia/Alcatel-Lucent 8661 server products.  These classes provide support
065 *   for proprietary functionality or for external specifications that are not
066 *   considered stable or mature enough to be guaranteed to work in an
067 *   interoperable way with other types of LDAP servers.
068 * </BLOCKQUOTE>
069 * <BR>
070 * This control is not based on any public standard, but was first introduced in
071 * the Netscape/iPlanet Directory Server.  It is also supported in the Sun Java
072 * System Directory Server, OpenDS, and the Ping Identity, UnboundID, and
073 * Nokia/Alcatel-Lucent 8661 Directory Server.  It does not have a value.
074 * <BR><BR>
075 * <H2>Example</H2>
076 * The following example demonstrates the use of the virtual attributes only
077 * request control:
078 * <PRE>
079 * SearchRequest searchRequest = new SearchRequest("dc=example,dc=com",
080 *      SearchScope.SUB, Filter.createEqualityFilter("uid", "john.doe"));
081 *
082 * searchRequest.addControl(new VirtualAttributesOnlyRequestControl());
083 * SearchResult searchResult = connection.search(searchRequest);
084 * </PRE>
