Member Function Documentation

const CommandLine& theplu::yat::utility::Option::cmd ( void  ) const

protectedinherited

Returns

const reference to CommandLine Option belongs to.

std::string theplu::yat::utility::Option::description ( void  ) const

inherited

Returns

description

void theplu::yat::utility::Option::description ( const std::string &  description )

inherited

set description

Since

New in yat 0.7

std::string theplu::yat::utility::Option::long_name ( void  ) const

inherited

Returns

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

bool theplu::yat::utility::Option::present ( void  ) const

inherited

Get if option was found in cmd.

Returns

true if option has been detected in parsing

std::string theplu::yat::utility::Option::print ( void  )

inherited

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

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()).
