LuyangSeqFluent

Collection Fluent API for C++. Like Java Stream, C# LINQ. It's Lazy!

std::vector<int> vec{ 1,2,3,4,5,6,7,8,9 };
auto iter = Seq(vec)
	>> Seq::Filter<int>([](int v) { return v % 2 == 0; })
	>> Seq::Take<int>(4)
	>> Seq::Map<int, std::string>([](int v) { return std::to_string(v + 100); })
	>> Seq::FlatMap<std::string, int>([](const std::string& v)
{
	std::vector<int> result;
	for (auto item : v)
	{
		result.push_back((int)item - 48);
	}
	return Seq(result);
});


while (iter->HasNext())
{
	auto next = iter->Next();
	std::cout << next << std::endl;
}
