// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
 * Service Description: `PrivateCatalog` allows catalog consumers to retrieve `Catalog`, `Product`
 * and `Version` resources under a target resource context.
 *
 * <p>`Catalog` is computed based on the [Association][]s linked to the target resource and its
 * ancestors. Each association's [google.cloud.privatecatalogproducer.v1beta.Catalog][] is
 * transformed into a `Catalog`. If multiple associations have the same parent
 * [google.cloud.privatecatalogproducer.v1beta.Catalog][], they are de-duplicated into one
 * `Catalog`. Users must have `cloudprivatecatalog.catalogTargets.get` IAM permission on the
 * resource context in order to access catalogs. `Catalog` contains the resource name and a subset
 * of data of the original [google.cloud.privatecatalogproducer.v1beta.Catalog][].
 *
 * <p>`Product` is child resource of the catalog. A `Product` contains the resource name and a
 * subset of the data of the original [google.cloud.privatecatalogproducer.v1beta.Product][].
 *
 * <p>`Version` is child resource of the product. A `Version` contains the resource name and a
 * subset of the data of the original [google.cloud.privatecatalogproducer.v1beta.Version][].
 *
 * <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 (PrivateCatalogClient privateCatalogClient = PrivateCatalogClient.create()) {
 *   SearchCatalogsRequest request =
 *       SearchCatalogsRequest.newBuilder()
 *           .setResource("resource-341064690")
 *           .setQuery("query107944136")
 *           .setPageSize(883849137)
 *           .setPageToken("pageToken873572522")
 *           .build();
 *   for (Catalog element : privateCatalogClient.searchCatalogs(request).iterateAll()) {
 *     // doThingsWith(element);
 *   }
 * }
 * }</pre>
 *
 * <p>Note: close() needs to be called on the PrivateCatalogClient 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 PrivateCatalogSettings 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
 * PrivateCatalogSettings privateCatalogSettings =
 *     PrivateCatalogSettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * PrivateCatalogClient privateCatalogClient = PrivateCatalogClient.create(privateCatalogSettings);
 * }</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
 * PrivateCatalogSettings privateCatalogSettings =
 *     PrivateCatalogSettings.newBuilder().setEndpoint(myEndpoint).build();
 * PrivateCatalogClient privateCatalogClient = PrivateCatalogClient.create(privateCatalogSettings);
 * }</pre>
 *
 * <p>To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
 * the wire:
 *
 * <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
 * PrivateCatalogSettings privateCatalogSettings =
 *     PrivateCatalogSettings.newBuilder()
 *         .setTransportChannelProvider(
 *             PrivateCatalogSettings.defaultHttpJsonTransportProviderBuilder().build())
 *         .build();
 * PrivateCatalogClient privateCatalogClient = PrivateCatalogClient.create(privateCatalogSettings);
 * }</pre>
 *
 * <p>Please refer to the GitHub repository's samples for more quickstart code snippets.
