| 28 | +// AUTO-GENERATED DOCUMENTATION AND CLASS. |
| 29 | +/** |
| 30 | + * Service Description: Provides other SQL dialects to GoogleSQL translation operations. |
| 31 | + * |
| 32 | + * <p>This class provides the ability to make remote calls to the backing service through method |
| 33 | + * calls that map to API methods. Sample code to get started: |
| 34 | + * |
| 35 | + * <pre>{@code |
| 36 | + * // This snippet has been automatically generated and should be regarded as a code template only. |
| 37 | + * // It will require modifications to work: |
| 38 | + * // - It may require correct/in-range values for request initialization. |
| 39 | + * // - It may require specifying regional endpoints when creating the service client as shown in |
| 40 | + * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library |
| 41 | + * try (SqlTranslationServiceClient sqlTranslationServiceClient = |
| 42 | + * SqlTranslationServiceClient.create()) { |
| 43 | + * LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]"); |
| 44 | + * TranslateQueryRequest.SqlTranslationSourceDialect sourceDialect = |
| 45 | + * TranslateQueryRequest.SqlTranslationSourceDialect.forNumber(0); |
| 46 | + * String query = "query107944136"; |
| 47 | + * TranslateQueryResponse response = |
| 48 | + * sqlTranslationServiceClient.translateQuery(parent, sourceDialect, query); |
| 49 | + * } |
| 50 | + * }</pre> |
| 51 | + * |
| 52 | + * <p>Note: close() needs to be called on the SqlTranslationServiceClient object to clean up |
| 53 | + * resources such as threads. In the example above, try-with-resources is used, which automatically |
| 54 | + * calls close(). |
| 55 | + * |
| 56 | + * <p>The surface of this class includes several types of Java methods for each of the API's |
| 57 | + * methods: |
| 58 | + * |
| 59 | + * <ol> |
| 60 | + * <li>A "flattened" method. With this type of method, the fields of the request type have been |
| 61 | + * converted into function parameters. It may be the case that not all fields are available as |
| 62 | + * parameters, and not every API method will have a flattened method entry point. |
| 63 | + * <li>A "request object" method. This type of method only takes one parameter, a request object, |
| 64 | + * which must be constructed before the call. Not every API method will have a request object |
| 65 | + * method. |
| 66 | + * <li>A "callable" method. This type of method takes no parameters and returns an immutable API |
| 67 | + * callable object, which can be used to initiate calls to the service. |
| 68 | + * </ol> |
| 69 | + * |
| 70 | + * <p>See the individual methods for example code. |
| 71 | + * |
| 72 | + * <p>Many parameters require resource names to be formatted in a particular way. To assist with |
| 73 | + * these names, this class includes a format method for each type of name, and additionally a parse |
| 74 | + * method to extract the individual identifiers contained within names that are returned. |
| 75 | + * |
| 76 | + * <p>This class can be customized by passing in a custom instance of SqlTranslationServiceSettings |
| 77 | + * to create(). For example: |
| 78 | + * |
| 79 | + * <p>To customize credentials: |
| 80 | + * |
| 81 | + * <pre>{@code |
| 82 | + * // This snippet has been automatically generated and should be regarded as a code template only. |
| 83 | + * // It will require modifications to work: |
| 84 | + * // - It may require correct/in-range values for request initialization. |
| 85 | + * // - It may require specifying regional endpoints when creating the service client as shown in |
| 86 | + * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library |
| 87 | + * SqlTranslationServiceSettings sqlTranslationServiceSettings = |
| 88 | + * SqlTranslationServiceSettings.newBuilder() |
| 89 | + * .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials)) |
| 90 | + * .build(); |
| 91 | + * SqlTranslationServiceClient sqlTranslationServiceClient = |
| 92 | + * SqlTranslationServiceClient.create(sqlTranslationServiceSettings); |
| 93 | + * }</pre> |
| 94 | + * |
| 95 | + * <p>To customize the endpoint: |
| 96 | + * |
| 97 | + * <pre>{@code |
| 98 | + * // This snippet has been automatically generated and should be regarded as a code template only. |
| 99 | + * // It will require modifications to work: |
| 100 | + * // - It may require correct/in-range values for request initialization. |
| 101 | + * // - It may require specifying regional endpoints when creating the service client as shown in |
| 102 | + * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library |
| 103 | + * SqlTranslationServiceSettings sqlTranslationServiceSettings = |
| 104 | + * SqlTranslationServiceSettings.newBuilder().setEndpoint(myEndpoint).build(); |
| 105 | + * SqlTranslationServiceClient sqlTranslationServiceClient = |
| 106 | + * SqlTranslationServiceClient.create(sqlTranslationServiceSettings); |
| 107 | + * }</pre> |
| 108 | + * |
| 109 | + * <p>To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over |
| 110 | + * the wire: |
| 111 | + * |
| 112 | + * <pre>{@code |
| 113 | + * // This snippet has been automatically generated and should be regarded as a code template only. |
| 114 | + * // It will require modifications to work: |
| 115 | + * // - It may require correct/in-range values for request initialization. |
| 116 | + * // - It may require specifying regional endpoints when creating the service client as shown in |
| 117 | + * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library |
| 118 | + * SqlTranslationServiceSettings sqlTranslationServiceSettings = |
| 119 | + * SqlTranslationServiceSettings.newHttpJsonBuilder().build(); |
| 120 | + * SqlTranslationServiceClient sqlTranslationServiceClient = |
| 121 | + * SqlTranslationServiceClient.create(sqlTranslationServiceSettings); |
| 122 | + * }</pre> |
| 123 | + * |
| 124 | + * <p>Please refer to the GitHub repository's samples for more quickstart code snippets. |
