Class MessagesV1Beta3Client

public class MessagesV1Beta3Client implements BackgroundResource

Service Description: The Dataflow Messages API is used for monitoring the progress of Dataflow jobs.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 try (MessagesV1Beta3Client messagesV1Beta3Client = MessagesV1Beta3Client.create()) {
   ListJobMessagesRequest request =
       ListJobMessagesRequest.newBuilder()
           .setProjectId("projectId-894832108")
           .setJobId("jobId101296568")
           .setMinimumImportance(JobMessageImportance.forNumber(0))
           .setPageSize(883849137)
           .setPageToken("pageToken873572522")
           .setStartTime(Timestamp.newBuilder().build())
           .setEndTime(Timestamp.newBuilder().build())
           .setLocation("location1901043637")
           .build();
   for (JobMessage element : messagesV1Beta3Client.listJobMessages(request).iterateAll()) {
     // doThingsWith(element);
   }
 }
 

Note: close() needs to be called on the MessagesV1Beta3Client object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

  1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
  2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
  3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of MessagesV1Beta3Settings to create(). For example:

To customize credentials:


 MessagesV1Beta3Settings messagesV1Beta3Settings =
     MessagesV1Beta3Settings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 MessagesV1Beta3Client messagesV1Beta3Client =
     MessagesV1Beta3Client.create(messagesV1Beta3Settings);
 

To customize the endpoint:


 MessagesV1Beta3Settings messagesV1Beta3Settings =
     MessagesV1Beta3Settings.newBuilder().setEndpoint(myEndpoint).build();
 MessagesV1Beta3Client messagesV1Beta3Client =
     MessagesV1Beta3Client.create(messagesV1Beta3Settings);

listJobMessages(ListJobMessagesRequest request)

public final MessagesV1Beta3Client.ListJobMessagesPagedResponse listJobMessages(ListJobMessagesRequest request)

Request the job status.

To request the status of a job, we recommend using projects.locations.jobs.messages.list with a regional endpoint. Using projects.jobs.messages.list is not recommended, as you can only request the status of jobs that are running in us-central1.

Sample code:


 try (MessagesV1Beta3Client messagesV1Beta3Client = MessagesV1Beta3Client.create()) {
   ListJobMessagesRequest request =
       ListJobMessagesRequest.newBuilder()
           .setProjectId("projectId-894832108")
           .setJobId("jobId101296568")
           .setMinimumImportance(JobMessageImportance.forNumber(0))
           .setPageSize(883849137)
           .setPageToken("pageToken873572522")
           .setStartTime(Timestamp.newBuilder().build())
           .setEndTime(Timestamp.newBuilder().build())
           .setLocation("location1901043637")
           .build();
   for (JobMessage element : messagesV1Beta3Client.listJobMessages(request).iterateAll()) {
     // doThingsWith(element);
   }
 }
 
Parameter
NameDescription
requestListJobMessagesRequest

The request object containing all of the parameters for the API call.

Returns
TypeDescription
MessagesV1Beta3Client.ListJobMessagesPagedResponse
