std::string theplu::yat::utility::Option::long_name

(

void

)

const

Returns:

long name e.g. 'help' for --help option.

bool theplu::yat::utility::Option::present

(

void

)

const

Get if option was found in cmd.

Returns:

true if option has been detected in parsing

std::string theplu::yat::utility::Option::print

(

void

)

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:

• print1 prints the short name, '-h', as short_name(void) const
• print2 prints the long name, '--help', as long_name(void) const
• print3 is empty
• print4 prints the description as description(void) const.

char theplu::yat::utility::Option::short_name

(

void

)

const

Returns:

short name e.g. 'h' for -h option.

void theplu::yat::utility::Option::validate

(

void

)

Validate the Option.

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