boost::unit_test::data::monomorphic::generated_by — Generators interface.
// In header: <boost/test/data/monomorphic/generate.hpp> template<typename Generator> class generated_by { public: // types typedef Generator::sample sample; typedef Generator generator_type; // member classes/structs/unions struct iterator { // construct/copy/destruct explicit iterator(Generator &); // public member functions sample const & operator *() const; void operator++(); }; enum @8 { arity = = 1 }; // construct/copy/destruct explicit generated_by(Generator &&); generated_by(generated_by &&); // public member functions data::size_t size() const; iterator begin() const; };
This class implements the dataset concept over a generator. Examples of generators are:
The generator concept is the following:
the type of the generated samples is given by field sample
the member function capacity should return the size of the collection being generated (potentially infinite)
the member function next should change the state of the generator to the next generated value
the member function reset should put the state of the object in the same state as right after its instanciation
