read_n() [1/2] std::tuple< VecColumn< Ts, 1 >... > read_n ( const TypedKey< Ts, TKey > &...  keys ) const Read a tuple of columns with given names or indices. Example usages: // Heterogeneous sequence (returns a tuple) auto columns = ext.read_n(as<int>("A"), as<float, 2>("B"), as<std::string>("C")); auto columns = ext.read_n(as<int>(0), as<float, 2>(3), as<std::string>(4)); // Homogeneous sequence (returns a vector) auto columns = ext.read_n<int, 2>({"A", "B", "C"}); auto columns = ext.read_n<int, 2>({0, 3, 4}); Warning Multidimensional columns are read as vector columns as of today.
