swig/Lib/std_except.i

// Typemaps used to handle and throw STD exceptions in a language
// and STL independent way, i.e., the target language doesn't
// require to support STL but only the 'exception.i' mechanism.
//
// These typemaps are used when methods are declared with an STD
// exception specification, such as
//
//   size_t at() const throw (std::out_of_range);
//
//
// As was said, the typemaps here are based in the language independent
// 'exception.i' library. If that is working in your target language,
// this file will work.
// 
// If the target language doesn't implement a robust 'exception.i'
// mechanism, or you prefer other ways to map the STD exceptions, write
// a new std_except.i file in the target library directory.
//
