+/**
+ * Service Description: Service for managing
+ * [Deployments][google.cloud.dialogflow.cx.v3.Deployment].
+ *
+ * <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
+ * try (DeploymentsClient deploymentsClient = DeploymentsClient.create()) {
+ *   DeploymentName name =
+ *       DeploymentName.of("[PROJECT]", "[LOCATION]", "[AGENT]", "[ENVIRONMENT]", "[DEPLOYMENT]");
+ *   Deployment response = deploymentsClient.getDeployment(name);
+ * }
+ * }</pre>
+ *
+ * <p>Note: close() needs to be called on the DeploymentsClient 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 DeploymentsSettings to
+ * create(). For example:
+ *
+ * <p>To customize credentials:
+ *
+ * <pre>{@code
+ * DeploymentsSettings deploymentsSettings =
+ *     DeploymentsSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * DeploymentsClient deploymentsClient = DeploymentsClient.create(deploymentsSettings);
+ * }</pre>
+ *
+ * <p>To customize the endpoint:
+ *
+ * <pre>{@code
+ * DeploymentsSettings deploymentsSettings =
+ *     DeploymentsSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * DeploymentsClient deploymentsClient = DeploymentsClient.create(deploymentsSettings);
+ * }</pre>
+ *
+ * <p>Please refer to the GitHub repository's samples for more quickstart code snippets.

+/**
+ * Settings class to configure an instance of {@link DeploymentsClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (dialogflow.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 total timeout of getDeployment to 30 seconds:
+ *
+ * <pre>{@code
+ * DeploymentsSettings.Builder deploymentsSettingsBuilder = DeploymentsSettings.newBuilder();
+ * deploymentsSettingsBuilder
+ *     .getDeploymentSettings()
+ *     .setRetrySettings(
+ *         deploymentsSettingsBuilder
+ *             .getDeploymentSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * DeploymentsSettings deploymentsSettings = deploymentsSettingsBuilder.build();
+ * }</pre>
