readSeqTo() [2/4] void readSeqTo ( TColumns &...  columns ) const Read a sequence of columns into existing Columns. Example usages: // Heterogeneous sequence (returns a tuple) auto columns = ext.readSeq(as<int>("A"), as<float, 2>("B"), as<std::string>("C")); auto columns = ext.readSeq(as<int>(0), as<float, 2>(3), as<std::string>(4)); // Homogeneous sequence (returns a vector) auto columns = ext.readSeq<int, 2>({"A", "B", "C"}); auto columns = ext.readSeq<int, 2>({0, 3, 4}); Warning Multidimensional columns are read as vector columns as of today.
