<p>If there are additional results, this is the token for the next set of results. If response includes <code>nextToken</code> there are two possible scenarios:</p> <ul> <li> <p>There are more segments so another call is required to get them.</p> </li> <li> <p>There are no more segments at this time, but more may be available later (real-time analysis is in progress) so the client should call the operation again to get new segments.</p> </li> </ul> <p>If response does not include <code>nextToken</code>, the analysis is completed (successfully or failed) and there are no more segments to retrieve.</p>
