Class template basic_option



// In header: <boost/program_options/option.hpp>

template<typename charT> 
class basic_option {
  // construct/copy/destruct
  basic_option(const std::string &, const std::vector< std::string > &);
  std::string string_key;
  int position_key;
  std::vector< std::basic_string< charT > > value;
  std::vector< std::basic_string< charT > > original_tokens;
  bool unregistered;


Option found in input source. Contains a key and a value. The key, in turn, can be a string (name of an option), or an integer (position in input source) -- in case no name is specified. The latter is only possible for command line. The template parameter specifies the type of char used for storing the option's value.
