+ * Service Description: Cloud OS Login API
+ *
+ * <p>The Cloud OS Login API allows you to manage users and their associated SSH public keys for
+ * logging into virtual machines on Google Cloud Platform.
+ *
+ * <p>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:
+ *
+ * <pre>{@code
+ * // 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 (OsLoginServiceClient osLoginServiceClient = OsLoginServiceClient.create()) {
+ *   UserName parent = UserName.of("[USER]");
+ *   OsLoginProto.SshPublicKey sshPublicKey = OsLoginProto.SshPublicKey.newBuilder().build();
+ *   OsLoginProto.SshPublicKey response =
+ *       osLoginServiceClient.createSshPublicKey(parent, sshPublicKey);
+ * }
+ * }</pre>
+ *
+ * <p>Note: close() needs to be called on the OsLoginServiceClient object to clean up resources such
+ * as threads. In the example above, try-with-resources is used, which automatically calls close().
+ *
+ * <table>

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link OsLoginServiceStub}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (oslogin.googleapis.com) and default port (443) are used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * <p>For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSshPublicKey:
+ *
+ * <pre>{@code
+ * // 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
+ * OsLoginServiceStubSettings.Builder osLoginServiceSettingsBuilder =
+ *     OsLoginServiceStubSettings.newBuilder();
+ * osLoginServiceSettingsBuilder
+ *     .createSshPublicKeySettings()
+ *     .setRetrySettings(
+ *         osLoginServiceSettingsBuilder
+ *             .createSshPublicKeySettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
