/**
*
* Represents the output for the
* {@link software.amazon.awssdk.services.connect.ConnectClient#searchContactFlowModulesPaginator(software.amazon.awssdk.services.connect.model.SearchContactFlowModulesRequest)}
* operation which is a paginated operation. This class is an iterable of
* {@link software.amazon.awssdk.services.connect.model.SearchContactFlowModulesResponse} 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.connect.paginators.SearchContactFlowModulesIterable responses = client.searchContactFlowModulesPaginator(request);
* responses.stream().forEach(....);
* }
*
*
* 2) Using For loop
*
*
* {
* @code
* software.amazon.awssdk.services.connect.paginators.SearchContactFlowModulesIterable responses = client
* .searchContactFlowModulesPaginator(request);
* for (software.amazon.awssdk.services.connect.model.SearchContactFlowModulesResponse response : responses) {
* // do something;
* }
* }
*
*
* 3) Use iterator directly
*
*
* {@code
* software.amazon.awssdk.services.connect.paginators.SearchContactFlowModulesIterable responses = client.searchContactFlowModulesPaginator(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 #searchContactFlowModules(software.amazon.awssdk.services.connect.model.SearchContactFlowModulesRequest)}
* operation.
*
