 *          <p>Retrieves an object's retention settings. For more information, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/object-lock.html">Locking Objects</a>.</p>
 *          <p>This functionality is not supported for Amazon S3 on Outposts.</p>
 *          <p>The following action is related to <code>GetObjectRetention</code>:</p>
 *          <ul>
 *             <li>
 *                <p>

 *             <p>You must URL encode any signed header values that contain spaces. For example, if your header value is <code>my  file.txt</code>, containing two spaces after <code>my</code>, you must URL encode this value to <code>my%20%20file.txt</code>.</p>

 * ```javascript
