/**
 * <p>Gets detailed information about a specified number of requests--a sample--that WAF
 *          randomly selects from among the first 5,000 requests that your Amazon Web Services resource received
 *          during a time range that you choose. You can specify a sample size of up to 500 requests,
 *          and you can specify any time range in the previous three hours.</p>
 *          <p>
 *             <code>GetSampledRequests</code> returns a time range, which is usually the time range that
 *          you specified. However, if your resource (such as a CloudFront distribution) received 5,000
 *          requests before the specified time range elapsed, <code>GetSampledRequests</code> returns
 *          an updated time range. This new time range indicates the actual period during which WAF
 *          selected the requests in the sample.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
