/**
 * Service Description: Service for managing [Pages][google.cloud.dialogflow.cx.v3beta1.Page].
 *
 * 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:
 *
 * 
{@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 (PagesClient pagesClient = PagesClient.create()) {
 *   PageName name = PageName.of("[PROJECT]", "[LOCATION]", "[AGENT]", "[FLOW]", "[PAGE]");
 *   Page response = pagesClient.getPage(name);
 * }
 * }
 *
 * Note: close() needs to be called on the PagesClient object to clean up resources such as
 * threads. In the example above, try-with-resources is used, which automatically calls close().

 ListPages  Returns the list of all pages in the specified flow.

 *      
 *            listPages(ListPagesRequest request)

 *      Request object method variants only take one parameter, a request object, which must be constructed before the call.
 *      
 *            getLocation(GetLocationRequest request)
 *      
 *      Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

 *            getLocationCallable()
 *      
 *       
 *
 * See the individual methods for example code.
 *
 * 
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.
 *
 * 
This class can be customized by passing in a custom instance of PagesSettings to create(). For
 * example:
 *
 * 
To customize credentials:
 *
 * 
{@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
 * PagesSettings pagesSettings =
 *     PagesSettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * PagesClient pagesClient = PagesClient.create(pagesSettings);
 * }
 *
 * To customize the endpoint:
 *
 * 
{@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
 * PagesSettings pagesSettings = PagesSettings.newBuilder().setEndpoint(myEndpoint).build();
 * PagesClient pagesClient = PagesClient.create(pagesSettings);
 * }
 *
 * To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
 * the wire:
 *
 * 
{@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
 * PagesSettings pagesSettings = PagesSettings.newHttpJsonBuilder().build();
 * PagesClient pagesClient = PagesClient.create(pagesSettings);
 * }
 *
 * Please refer to the GitHub repository's samples for more quickstart code snippets.
