/**
 * This class provides an implementation of the virtual attributes only request
 * control, which may be included in a search request to indicate that only
 * virtual attributes should be included in matching entries.
 * 

 * 

 *   NOTE:  This class, and other classes within the
 *   {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
 *   supported for use against Ping Identity, UnboundID, and
 *   Nokia/Alcatel-Lucent 8661 server products.  These classes provide support
 *   for proprietary functionality or for external specifications that are not
 *   considered stable or mature enough to be guaranteed to work in an
 *   interoperable way with other types of LDAP servers.
 * 
 * 

 * This control is not based on any public standard, but was first introduced in
 * the Netscape/iPlanet Directory Server.  It is also supported in the Sun Java
 * System Directory Server, OpenDS, and the Ping Identity, UnboundID, and
 * Nokia/Alcatel-Lucent 8661 Directory Server.  It does not have a value.
 * 


 * 
Example
 * The following example demonstrates the use of the virtual attributes only
 * request control:
 * 
 * SearchRequest searchRequest = new SearchRequest("dc=example,dc=com",
 *      SearchScope.SUB, Filter.createEqualityFilter("uid", "john.doe"));
 *
 * searchRequest.addControl(new VirtualAttributesOnlyRequestControl());
 * SearchResult searchResult = connection.search(searchRequest);
 *
