+/**
+ * Service Description: Service that executes SpannerActions asynchronously.
+ *
+ * <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 (SpannerExecutorProxyClient spannerExecutorProxyClient =
+ *     SpannerExecutorProxyClient.create()) {
+ *   BidiStream<SpannerAsyncActionRequest, SpannerAsyncActionResponse> bidiStream =
+ *       spannerExecutorProxyClient.executeActionAsyncCallable().call();
+ *   SpannerAsyncActionRequest request =
+ *       SpannerAsyncActionRequest.newBuilder()
+ *           .setActionId(198295492)
+ *           .setAction(SpannerAction.newBuilder().build())
+ *           .build();
+ *   bidiStream.send(request);
+ *   for (SpannerAsyncActionResponse response : bidiStream) {
+ *     // Do something when a response is received.
+ *   }
+ * }
+ * }</pre>
+ *
+ * <p>Note: close() needs to be called on the SpannerExecutorProxyClient object to clean up
+ * resources such as threads. In the example above, try-with-resources is used, which automatically
+ * calls close().
+ *
+ * <p>The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * <ol>
+ *   <li>A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   <li>A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   <li>A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * </ol>
+ *
+ * <p>See the individual methods for example code.
+ *
+ * <p>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.
+ *
+ * <p>This class can be customized by passing in a custom instance of SpannerExecutorProxySettings
+ * to create(). For example:
+ *
+ * <p>To customize credentials:
+ *
+ * <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
+ * SpannerExecutorProxySettings spannerExecutorProxySettings =
+ *     SpannerExecutorProxySettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * SpannerExecutorProxyClient spannerExecutorProxyClient =
+ *     SpannerExecutorProxyClient.create(spannerExecutorProxySettings);
+ * }</pre>
+ *
+ * <p>To customize the endpoint:
+ *
+ * <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
+ * SpannerExecutorProxySettings spannerExecutorProxySettings =
+ *     SpannerExecutorProxySettings.newBuilder().setEndpoint(myEndpoint).build();
+ * SpannerExecutorProxyClient spannerExecutorProxyClient =
+ *     SpannerExecutorProxyClient.create(spannerExecutorProxySettings);
+ * }</pre>
+ *
+ * <p>Please refer to the GitHub repository's samples for more quickstart code snippets.
