@Generated(value="software.amazon.awssdk:codegen") public class DescribeDataProvidersPublisher extends Object implements SdkPublisher<DescribeDataProvidersResponse>
Represents the output for the
DatabaseMigrationAsyncClient.describeDataProvidersPaginator(software.amazon.awssdk.services.databasemigration.model.DescribeDataProvidersRequest)
operation which is a paginated operation. This class is a type of Publisher which can be
used to provide a sequence of
DescribeDataProvidersResponse 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.databasemigration.paginators.DescribeDataProvidersPublisher publisher = client.describeDataProvidersPaginator(request);
CompletableFuture<Void> future = publisher.subscribe(res -> { // Do something with the response });
future.get();
2) Using a custom subscriber
software.amazon.awssdk.services.databasemigration.paginators.DescribeDataProvidersPublisher publisher = client.describeDataProvidersPaginator(request);
publisher.subscribe(new Subscriber<software.amazon.awssdk.services.databasemigration.model.DescribeDataProvidersResponse>() {
public void onSubscribe(org.reactivestreams.Subscriber subscription) { //... };
public void onNext(software.amazon.awssdk.services.databasemigration.model.DescribeDataProvidersResponse response) { //... };
});
As the response is a publisher, it can work well with third party reactive streams implementations like RxJava2.
Please notice that the configuration of MaxRecords 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
#describeDataProviders(software.amazon.awssdk.services.databasemigration.model.DescribeDataProvidersRequest)
operation.
