Class DescribeDBLogFilesPublisher

  • All Implemented Interfaces:
    org.reactivestreams.Publisher<DescribeDbLogFilesResponse>, SdkPublisher<DescribeDbLogFilesResponse>
    @Generated("software.amazon.awssdk:codegen")
public class DescribeDBLogFilesPublisher
extends Object
implements SdkPublisher<DescribeDbLogFilesResponse>

    Represents the output for the RdsAsyncClient.describeDBLogFilesPaginator(software.amazon.awssdk.services.rds.model.DescribeDbLogFilesRequest) operation which is a paginated operation. This class is a type of Publisher which can be used to provide a sequence of DescribeDbLogFilesResponse 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.rds.paginators.DescribeDBLogFilesPublisher publisher = client.describeDBLogFilesPaginator(request);
 CompletableFuture<Void> future = publisher.subscribe(res -> { // Do something with the response });
 future.get();
    2) Using a custom subscriber 
     
 software.amazon.awssdk.services.rds.paginators.DescribeDBLogFilesPublisher publisher = client.describeDBLogFilesPaginator(request);
 publisher.subscribe(new Subscriber<software.amazon.awssdk.services.rds.model.DescribeDbLogFilesResponse>() {
 
 public void onSubscribe(org.reactivestreams.Subscriber subscription) { //... };
 
 
 public void onNext(software.amazon.awssdk.services.rds.model.DescribeDbLogFilesResponse 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 #describeDBLogFiles(software.amazon.awssdk.services.rds.model.DescribeDbLogFilesRequest) operation.

    • Method Detail

      • describeDBLogFiles

        public final SdkPublisher<DescribeDBLogFilesDetails> describeDBLogFiles()
        Returns a publisher that can be used to get a stream of data. You need to subscribe to the publisher to request the stream of data. The publisher has a helper forEach method that takes in a Consumer and then applies that consumer to each response returned by the service.
