Class template singleton

boost::unit_test::data::monomorphic::singleton — Models a single element data set.


// In header: <boost/test/data/monomorphic/singleton.hpp>

template<typename T> 
class singleton {
  // member classes/structs/unions

  struct iterator {
    // construct/copy/destruct
    explicit iterator(singleton< T > const *);

    // public member functions
    sample const  & operator *() const;
    void operator++();

  enum @11 { arity = = 1 };
  // construct/copy/destruct
  explicit singleton(T &&);
  singleton(singleton &&);

  // public member functions
  T const  & value() const;
  data::size_t size() const;
  iterator begin() const;
