@Generated(value="software.amazon.awssdk:codegen") public class ListTopicsDetectionJobsPublisher extends Object implements SdkPublisher<ListTopicsDetectionJobsResponse>
Represents the output for the
ComprehendAsyncClient.listTopicsDetectionJobsPaginator(software.amazon.awssdk.services.comprehend.model.ListTopicsDetectionJobsRequest)
operation which is a paginated operation. This class is a type of Publisher
which can be
used to provide a sequence of
ListTopicsDetectionJobsResponse
response pages as per demand
from the subscriber.
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. If there are errors in your request, you will see the failures
only after you start streaming the data. The subscribe method should be called as a request to start streaming data.
For more info, see Publisher.subscribe(org.reactivestreams.Subscriber)
. Each call to the
subscribe method will result in a new Subscription
i.e., a new contract to stream data
from the starting request.
The following are few ways to use the response class:
1) Using the forEach helper method
software.amazon.awssdk.services.comprehend.paginators.ListTopicsDetectionJobsPublisher publisher = client.listTopicsDetectionJobsPaginator(request);
CompletableFuture<Void> future = publisher.forEach(res -> { // Do something with the response });
future.get();
2) Using a custom subscriber
software.amazon.awssdk.services.comprehend.paginators.ListTopicsDetectionJobsPublisher publisher = client.listTopicsDetectionJobsPaginator(request);
publisher.subscribe(new Subscriber<software.amazon.awssdk.services.comprehend.model.ListTopicsDetectionJobsResponse>() {
public void onSubscribe(org.reactivestreams.Subscriber subscription) { //... };
public void onNext(software.amazon.awssdk.services.comprehend.model.ListTopicsDetectionJobsResponse response) { //... };
});
As the response is a publisher, it can work well with third party reactive streams implementations like RxJava2.
Note: If you prefer to have control on service calls, use the
#listTopicsDetectionJobs(software.amazon.awssdk.services.comprehend.model.ListTopicsDetectionJobsRequest)
operation.

public final ListTopicsDetectionJobsPublisher resume(ListTopicsDetectionJobsResponse lastSuccessfulPage)
A helper method to resume the pages in case of unexpected failures. The method takes the last successful response
page as input and returns an instance of ListTopicsDetectionJobsPublisher
that can be used to retrieve
the consecutive pages that follows the input page.
