/**
 * This class provides an implementation of a Directory Server control that may
 * be used to indicate that the associated operation is used for performing some
 * administrative operation within the server rather than one that was requested
 * by a "normal" client.  The server can use this indication to treat the
 * operation differently (e.g., exclude it from the processing time histogram,
 * or to include additional information about the purpose of the operation in
 * the access log).
 * 

 * 
 *   NOTE:  This class is part of the Commercial Edition of the UnboundID
 *   LDAP SDK for Java.  It is not available for use in applications that
 *   include only the Standard Edition of the LDAP SDK, and is not supported for
 *   use in conjunction with non-UnboundID products.
