Class template grid

boost::unit_test::data::monomorphic::grid — Implements the dataset resulting from a cartesian product/grid operation on datasets.

Synopsis

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

template<typename DS1, typename DS2> 
class grid {
public:
  // member classes/structs/unions

  struct iterator :
    public boost::unit_test::data::monomorphic::dataset< T >::iterator
  {
    // types
    typedef monomorphic::traits< T >::ref_type ref_type;

    // construct/copy/destruct
    explicit iterator(ds1_iter_ptr, DS2 const &);

    // public member functions
    virtual ref_type operator*();
    virtual void operator++();
  };

  enum @6 { 
            arity = = boost::decay<DS1>::type::arity + boost::decay<DS2>::type::arity };
  // construct/copy/destruct
  grid(DS1 &&, DS2 &&);
  grid(grid &&);

  // public member functions
  virtual data::size_t size() const;
  virtual iter_ptr begin() const;
};

Description

The arity of the resulting dataset is the sum of the arity of its operands.

`grid` public construct/copy/destruct

```
grid(DS1 && ds1, DS2 && ds2);
```
Constructor.
```
grid(grid && j);
```
Move constructor.

`grid` public member functions

```
virtual data::size_t size() const;
```
Dataset size.
```
virtual iter_ptr begin() const;
```
Iterator to use to iterate over this dataset.
