/**
* Base class for REST API controllers defined inside the 'src' directory.
*
* Besides implementing the abstract methods, derived classes must be registered in the dependency injection
* container with the 'share_with_implements_tags' method inside a service provider that inherits from
* 'AbstractInterfaceServiceProvider'. This ensures that 'register_routes' is invoked.
*
* Derived classes must also contain this line:
* use Automattic\WooCommerce\Internal\Traits\AccessiblePrivateMethods;
*
* Minimal controller example:
*
* class FoobarsController extends RestApiControllerBase {
*
* use Automattic\WooCommerce\Internal\Traits\AccessiblePrivateMethods;
*
* protected function get_rest_api_namespace(): string {
* return 'foobars';
* }
*
* public function register_routes() {
* register_rest_route(
* $this->route_namespace,
* '/foobars/(?P<id>[\d]+)',
* array(
* array(
* 'methods' => \WP_REST_Server::READABLE,
* 'callback' => fn( $request ) => $this->run( $request, 'get_foobar' ),
* 'permission_callback' => fn( $request ) => $this->check_permission( $request, 'read_foobars', $request->get_param( 'id' ) ),
* 'args' => $this->get_args_for_get_foobar(),
* 'schema' => $this->get_schema_for_get_foobar(),
* ),
* )
* );
* }
*
* protected function get_foobar( \WP_REST_Request $request ) {
* return array( 'message' => 'Get foobar with id ' . $request->get_param(' id' ) );
* }
*
* private function get_args_for_get_foobar(): array {
* return array(
* 'id' => array(
* 'description' => __( 'Unique identifier of the foobar.', 'woocommerce' ),
* 'type' => 'integer',
* 'context' => array( 'view', 'edit' ),
* 'readonly' => true,
* ),
* );
* }
*
* private function get_schema_for_get_foobar(): array {
* $schema = $this->get_base_schema();
* $schema['properties'] = array(
* 'message' => array(
* 'description' => __( 'A message.', 'woocommerce' ),
* 'type' => 'string',
* 'context' => array( 'view', 'edit' ),
* 'readonly' => true,
