public class PollForDecisionTaskIterable
extends Object
implements SdkIterable<PollForDecisionTaskResponse>

    Represents the output for the SwfClient.pollForDecisionTaskPaginator(software.amazon.awssdk.services.swf.model.PollForDecisionTaskRequest) operation which is a paginated operation. This class is an iterable of PollForDecisionTaskResponse 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 
     
 software.amazon.awssdk.services.swf.paginators.PollForDecisionTaskIterable responses = client.pollForDecisionTaskPaginator(request);
 responses.stream().forEach(....);
    2) Using For loop 
     {
     @code
     software.amazon.awssdk.services.swf.paginators.PollForDecisionTaskIterable responses = client
             .pollForDecisionTaskPaginator(request);
     for (software.amazon.awssdk.services.swf.model.PollForDecisionTaskResponse response : responses) {
         // do something;
     }
 }
    3) Use iterator directly 
     
 software.amazon.awssdk.services.swf.paginators.PollForDecisionTaskIterable responses = client.pollForDecisionTaskPaginator(request);
 responses.iterator().forEachRemaining(....);

    Please notice that the configuration of maximumPageSize 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 #pollForDecisionTask(software.amazon.awssdk.services.swf.model.PollForDecisionTaskRequest) operation.
