@Generated(value="software.amazon.awssdk:codegen") public class DescribeStackResourceDriftsPublisher extends Object implements SdkPublisher<DescribeStackResourceDriftsResponse>
Represents the output for the
CloudFormationAsyncClient.describeStackResourceDriftsPaginator(software.amazon.awssdk.services.cloudformation.model.DescribeStackResourceDriftsRequest)
operation which is a paginated operation. This class is a type of Publisher which can be
used to provide a sequence of
DescribeStackResourceDriftsResponse 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 subscribe helper method
software.amazon.awssdk.services.cloudformation.paginators.DescribeStackResourceDriftsPublisher publisher = client.describeStackResourceDriftsPaginator(request);
CompletableFuture<Void> future = publisher.subscribe(res -> { // Do something with the response });
future.get();
2) Using a custom subscriber
software.amazon.awssdk.services.cloudformation.paginators.DescribeStackResourceDriftsPublisher publisher = client.describeStackResourceDriftsPaginator(request);
publisher.subscribe(new Subscriber<software.amazon.awssdk.services.cloudformation.model.DescribeStackResourceDriftsResponse>() {
public void onSubscribe(org.reactivestreams.Subscriber subscription) { //... };
public void onNext(software.amazon.awssdk.services.cloudformation.model.DescribeStackResourceDriftsResponse 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
#describeStackResourceDrifts(software.amazon.awssdk.services.cloudformation.model.DescribeStackResourceDriftsRequest)
operation.
