class delayed_dataset {
public:
  // types
  typedef decltype(std::declval< dataset_t >().begin()) iterator;

  // construct/copy/destruct
  delayed_dataset(Args...);
  delayed_dataset(delayed_dataset &&);

  // public member functions
  boost::unit_test::data::size_t size() const;
  iterator begin() const;

  // private member functions
  dataset_t & get() const;
  template<std::size_t... I>

Description

This dataset holds another dataset that is instanciated on demand. It is constructed with the data::make_delayed<dataset_t>(arg1,....) instead of the data::make.

delayed_dataset public construct/copy/destruct

  1. delayed_dataset(Args... args);
  2. delayed_dataset(delayed_dataset && b);

delayed_dataset public member functions

  1. boost::unit_test::data::size_t size() const;
  2. iterator begin() const;

delayed_dataset private member functions

  1. dataset_t & get() const;
  2. template<std::size_t... I> 
      std::unique_ptr< dataset_t > 
      create(boost::unit_test::data::index_sequence< I... >) const;
