Class SchemaServiceClient (1.135.0)

GitHub RepositoryProduct Reference

Service Description: Service for doing schema-related operations.

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 (SchemaServiceClient schemaServiceClient = SchemaServiceClient.create()) {
   ProjectName parent = ProjectName.of("[PROJECT]");
   Schema schema = Schema.newBuilder().build();
   String schemaId = "schemaId-697673060";
   Schema response = schemaServiceClient.createSchema(parent, schema, schemaId);
 }

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

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 SchemaServiceSettings 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
 SchemaServiceSettings schemaServiceSettings =
     SchemaServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 SchemaServiceClient schemaServiceClient = SchemaServiceClient.create(schemaServiceSettings);

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
 SchemaServiceSettings schemaServiceSettings =
     SchemaServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 SchemaServiceClient schemaServiceClient = SchemaServiceClient.create(schemaServiceSettings);

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
 SchemaServiceSettings schemaServiceSettings =
     SchemaServiceSettings.newHttpJsonBuilder().build();
 SchemaServiceClient schemaServiceClient = SchemaServiceClient.create(schemaServiceSettings);
