/**
 * 
 * Represents the output for the
 * {@link software.amazon.awssdk.services.applicationdiscovery.ApplicationDiscoveryClient#describeContinuousExportsPaginator(software.amazon.awssdk.services.applicationdiscovery.model.DescribeContinuousExportsRequest)}
 * operation which is a paginated operation. This class is an iterable of
 * {@link software.amazon.awssdk.services.applicationdiscovery.model.DescribeContinuousExportsResponse} that can be used
 * to iterate through all the response pages of the operation.
 * 
 * 
 * When the operation is called, an instance of this class is returned. At this point, no service calls are made yet and
 * so there is no guarantee that the request is valid. As you iterate through the iterable, SDK will start lazily
 * loading response pages by making service calls until there are no pages left or your iteration stops. If there are
 * errors in your request, you will see the failures only after you start iterating through the iterable.
 * 
 *
 * 
 * The following are few ways to iterate through the response pages:
 * 
 * 1) Using a Stream
 * 
 *  * {@code
 * software.amazon.awssdk.services.applicationdiscovery.paginators.DescribeContinuousExportsIterable responses = client.describeContinuousExportsPaginator(request);
 * responses.stream().forEach(....);
 * }
 * 
 *
 * 2) Using For loop
 * 
 *  * {
 *     @code
 *     software.amazon.awssdk.services.applicationdiscovery.paginators.DescribeContinuousExportsIterable responses = client
 *             .describeContinuousExportsPaginator(request);
 *     for (software.amazon.awssdk.services.applicationdiscovery.model.DescribeContinuousExportsResponse response : responses) {
 *         // do something;
 *     }
 * }
 * 
 *
 * 3) Use iterator directly
 * 
 *  * {@code
 * software.amazon.awssdk.services.applicationdiscovery.paginators.DescribeContinuousExportsIterable responses = client.describeContinuousExportsPaginator(request);
 * responses.iterator().forEachRemaining(....);
 * }
 * 
 * 
 * Please notice that the configuration of maxResults won't limit the number of results you get with the paginator.
 * It only limits the number of results in each page.
 * 
 * 
 * Note: If you prefer to have control on service calls, use the
 * {@link #describeContinuousExports(software.amazon.awssdk.services.applicationdiscovery.model.DescribeContinuousExportsRequest)}
 * operation.
 *
