boost::unit_test::data::xrange — Creates a range (sequence) dataset.
// In header: <boost/test/data/monomorphic/generators/xrange.hpp> template<typename SampleType, typename Params> monomorphic::generated_by< monomorphic::xrange_t< SampleType > > xrange(Params const & params);
The following overloads are available:
auto d = xrange(); auto d = xrange(end_val); auto d = xrange(end_val, param); auto d = xrange(begin_val, end_val); auto d = xrange(begin_val, end_val, step_val); auto d = xrange(param);
begin_val indicates the start of the sequence (default to 0).
end_val is the end of the sequence. If ommited, the dataset has infinite size.
step_val is the step between two consecutive elements of the sequence, and defaults to 1.
param is the named parameters that describe the sequence. The following parameters are accepted:
begin: same meaning begin_val
end: same meaning as end_val
step: same meaning as step_val
The returned value is an object that implements the dataset API.
