Class template collection

boost::unit_test::data::monomorphic::collection — Dataset from a forward iterable container (collection)

Synopsis

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

template<typename C> 
class collection : public boost::unit_test::data::monomorphic::dataset< boost::decay< C >::type::value_type >
{
public:
  // member classes/structs/unions

  struct iterator :
    public boost::unit_test::data::monomorphic::dataset< T >::iterator
  {
    // construct/copy/destruct
    explicit iterator(collection< C > const &);

    // public member functions
    virtual T const & operator*();
    virtual void operator++();
  };

  enum @4 { arity = = 1 };
  // construct/copy/destruct
  explicit collection(C &&);
  collection(collection &&);

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

Description

This dataset is applicable to any container implementing a forward iterator. Note that container with one element will be considered as singletons. This dataset is constructible with the boost::unit_test::data::make function.

For compilers supporting r-value references, the collection is moved instead of copied.

`collection` public construct/copy/destruct

```
explicit collection(C && col);
```
Constructor The collection is moved.
```
collection(collection && c);
```
Move constructor.

`collection` public member functions

```
C const & col() const;
```
Returns the underlying collection.
```
virtual data::size_t size() const;
```
Dataset size.
```
virtual iter_ptr begin() const;
```
Iterator to use to iterate over this dataset.
