◆ GetVal()

template<class T >

T cyclus::QueryResult::GetVal	(	std::string	field,
		int	row = 0 )

Convenience method for retrieving a value from a specific row and named field (column).

The caller is responsible for specifying a valid templated type to cast to. Example use:

QueryResult qr = ...
 
for (int i = 0; i < qr.rows.size(); ++i) {
  std::cout << qr.GetVal<int>("field1", i) << "\n";
  std::cout << qr.GetVal<double>("field2", i) << "\n";
  std::cout << qr.GetVal<std::string>("field3", i) << "\n";
}
