Class SchemaServiceClient (0.38.0)

GitHub RepositoryProduct Reference

Service Description: Service for managing Schemas.

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()) {
   SchemaName name =
       SchemaName.ofProjectLocationDataStoreSchemaName(
           "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[SCHEMA]");
   Schema response = schemaServiceClient.getSchema(name);
 }

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().

Methods
Method Description Method Variants

GetSchema

Gets a Schema.

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

  • getSchema(GetSchemaRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • getSchema(SchemaName name)

  • getSchema(String name)

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

  • getSchemaCallable()

ListSchemas

Gets a list of Schemas.

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

  • listSchemas(ListSchemasRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • listSchemas(DataStoreName parent)

  • listSchemas(String parent)

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

  • listSchemasPagedCallable()

  • listSchemasCallable()

CreateSchema

Creates a Schema.

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

  • createSchemaAsync(CreateSchemaRequest request)

Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service.

  • createSchemaAsync(DataStoreName parent, Schema schema, String schemaId)

  • createSchemaAsync(String parent, Schema schema, String schemaId)

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

  • createSchemaOperationCallable()

  • createSchemaCallable()

UpdateSchema

Updates a Schema.

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

  • updateSchemaAsync(UpdateSchemaRequest request)

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

  • updateSchemaOperationCallable()

  • updateSchemaCallable()

DeleteSchema

Deletes a Schema.

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

  • deleteSchemaAsync(DeleteSchemaRequest request)

Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service.

  • deleteSchemaAsync(SchemaName name)

  • deleteSchemaAsync(String name)

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

  • deleteSchemaOperationCallable()

  • deleteSchemaCallable()

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);
