print help output

This function calls the four virtual private functions print1, print2, print3, and print4. This allows an inherited class to implement one (or several) of these functions and keep the default output of the others. The default behavior is that:

char theplu::yat::utility::Option::short_name ( void  ) const
inherited
Returns
short name e.g. 'h' for -h option.
void theplu::yat::utility::Option::validate ( void  )
inherited

Validate the Option.

This function is called by CommandLine::parse() after all options have been detected and parsed (see Option::parse()).
