Class TemplatesServiceClient (0.50.0)

GitHub RepositoryProduct ReferenceREST DocumentationRPC Documentation

Service Description: Provides a method to create Cloud Dataflow jobs from templates.

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:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (TemplatesServiceClient templatesServiceClient = TemplatesServiceClient.create()) {
   CreateJobFromTemplateRequest request =
       CreateJobFromTemplateRequest.newBuilder()
           .setProjectId("projectId-894832108")
           .setJobName("jobName-1438096408")
           .putAllParameters(new HashMap<String, String>())
           .setEnvironment(RuntimeEnvironment.newBuilder().build())
           .setLocation("location1901043637")
           .build();
   Job response = templatesServiceClient.createJobFromTemplate(request);
 }

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

Methods
Method Description Method Variants

CreateJobFromTemplate

Creates a Cloud Dataflow job from a template.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • createJobFromTemplate(CreateJobFromTemplateRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • createJobFromTemplateCallable()

LaunchTemplate

Launch a template.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • launchTemplate(LaunchTemplateRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • launchTemplateCallable()

GetTemplate

Get the template associated with a template.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • getTemplate(GetTemplateRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • getTemplateCallable()

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 TemplatesServiceSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 TemplatesServiceSettings templatesServiceSettings =
     TemplatesServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 TemplatesServiceClient templatesServiceClient =
     TemplatesServiceClient.create(templatesServiceSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 TemplatesServiceSettings templatesServiceSettings =
     TemplatesServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 TemplatesServiceClient templatesServiceClient =
     TemplatesServiceClient.create(templatesServiceSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 TemplatesServiceSettings templatesServiceSettings =
     TemplatesServiceSettings.newHttpJsonBuilder().build();
 TemplatesServiceClient templatesServiceClient =
     TemplatesServiceClient.create(templatesServiceSettings);
