  /**
   * <p>AppConfig Data provides the data plane APIs your application uses to retrieve
   * configuration data. Here's how it works:</p> <p>Your application retrieves
   * configuration data by first establishing a configuration session using the
   * AppConfig Data <a>StartConfigurationSession</a> API action. Your session's
   * client then makes periodic calls to <a>GetLatestConfiguration</a> to check for
   * and retrieve the latest data available.</p> <p>When calling
   * <code>StartConfigurationSession</code>, your code sends the following
   * information:</p> <ul> <li> <p>Identifiers (ID or name) of an AppConfig
   * application, environment, and configuration profile that the session tracks.</p>
   * </li> <li> <p>(Optional) The minimum amount of time the session's client must
   * wait between calls to <code>GetLatestConfiguration</code>.</p> </li> </ul> <p>In
   * response, AppConfig provides an <code>InitialConfigurationToken</code> to be
   * given to the session's client and used the first time it calls
   * <code>GetLatestConfiguration</code> for that session.</p>  <p>This
   * token should only be used once in your first call to
   * <code>GetLatestConfiguration</code>. You <i>must</i> use the new token in the
   * <code>GetLatestConfiguration</code> response
   * (<code>NextPollConfigurationToken</code>) in each subsequent call to
   * <code>GetLatestConfiguration</code>.</p>  <p>When calling
   * <code>GetLatestConfiguration</code>, your client code sends the most recent
   * <code>ConfigurationToken</code> value it has and receives in response:</p> <ul>
   * <li> <p> <code>NextPollConfigurationToken</code>: the
   * <code>ConfigurationToken</code> value to use on the next call to
   * <code>GetLatestConfiguration</code>.</p> </li> <li> <p>
   * <code>NextPollIntervalInSeconds</code>: the duration the client should wait
   * before making its next call to <code>GetLatestConfiguration</code>. This
   * duration may vary over the course of the session, so it should be used instead
   * of the value sent on the <code>StartConfigurationSession</code> call.</p> </li>
   * <li> <p>The configuration: the latest data intended for the session. This may be
   * empty if the client already has the latest version of the configuration.</p>
   * </li> </ul>  <p>The <code>InitialConfigurationToken</code> and
   * <code>NextPollConfigurationToken</code> should only be used once. To support
   * long poll use cases, the tokens are valid for up to 24 hours. If a
   * <code>GetLatestConfiguration</code> call uses an expired token, the system
   * returns <code>BadRequestException</code>.</p>  <p>For more
   * information and to view example CLI commands that show how to retrieve a
   * configuration using the AppConfig Data <code>StartConfigurationSession</code>
   * and <code>GetLatestConfiguration</code> API actions, see <a
   * href="http://docs.aws.amazon.com/appconfig/latest/userguide/appconfig-retrieving-the-configuration">Retrieving
   * the configuration</a> in the <i>AppConfig User Guide</i>.</p>
