Product 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);
 

Please refer to the GitHub repository's samples for more quickstart code snippets.
