How to work with php cache on the new 1C-Bitrix core?

Question

1C-Bitrix

Hello! On the old kernel I write like this:

$obCache = new \CPHPCache();
$cacheID = 'cache';
$cachePath = '/'.self::MODULE_ID.'/'.$cacheID;
if ($obCache->InitCache(3600, $cacheID, $cachePath)) {
    $vars = $obCache->GetVars();
    extract($vars);
} else if ($obCache->StartDataCache()) {
    // кеш отсутствует
    $obCache->EndDataCache(['result' => $result]);
}

There is a /bitrix/modules/main/lib/data/cache.php file in the new core, but the example cannot be found, even on offsite. Who worked with the new d7, show an example of working with the cache.

use \Bitrix\Main\Data\cache;

$cache = cache::createInstance();

if( $cache->initCache( $ttl, $id, $id ) ){
  $res = $cache->getVars();
  $arRes = $res["arRes"];
}else{
  $res = array();
  try{
    $cache->startDataCache( $ttl, $id, $id );
    $cache->endDataCache( array(
      "arRes" => $arRes
    ) );
  }catch( SystemException $e ){
    $cache->abortDataCache();
    ShowError( $e->getMessage() );
  }
}
