Does this code snippet use Repository or Adapter pattern?
public interface ICacheProvider
{
  void Store(string key, object data);
  void Destroy(string key);
  T Get<T>(string key);
}

public class CacheManager
{
  protected ICacheProvider _repository;
  public CacheManager(ICacheProvider repository)
  {
      _repository = repository;
  }

  public void Store(string key, object data)
  {
      _repository.Store(key, data);
  }

  public void Destroy(string key)
  {
      _repository.Destroy(key);
  }

  public T Get<T>(string key)
  {
      return _repository.Get<T>(key);
  }
}

public class SessionProvider : ICacheProvider
{
  public void Store(string key, object data)
  {
      HttpContext.Current.Cache.Insert(key, data);
  }

  public void Destroy(string key)
  {
      HttpContext.Current.Cache.Remove(key);
  }

  public T Get<T>(string key)
  {
      T item = default(T);
      if (HttpContext.Current.Cache[key] != null)
      {
          item = (T)HttpContext.Current.Cache[key];
      }
      return item;
  }
}
