Detailed Description

Class for file related options.

Deprecated:

Provided for backward compatibility with the 0.5 API. Use OptionFile and StreamRedirect instead (see CommandLine for example code).

Constructor & Destructor Documentation

OptionOutFile()

theplu::yat::utility::OptionOutFile::OptionOutFile	(	CommandLine &	cmd,
		std::string	name,
		std::string	desc,
		bool	required = false
	)

Constructor.

Parameters

cmd	Commandline Option is associated with
name	string such as "file" for –file, "f" for -f or "f,file" for having both short and long option name
desc	string used in help display
required	If true option must be found in commandline or exception is thrown in validation

Member Function Documentation

cmd()

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

protectedinherited

Returns

const reference to CommandLine Option belongs to.

description() [1/2]

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

inherited

Returns

description

description() [2/2]

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

inherited

set description

Since

New in yat 0.7

long_name()

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

inherited

Returns

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

present()

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

print()

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.

print_arg()

void theplu::yat::utility::OptionArg< std::string >::print_arg ( std::string  arg )

inlineinherited

Parameters

arg	string to be used in help output such as '=TARGET' in '–target=TARGET'. See print3().

Since

New in yat 0.5.

required()

bool theplu::yat::utility::OptionArg< std::string >::required ( void  ) const

inlineprotectedinherited

Returns

true if Option is required, i.e., if Option is not found during parsing an exception will be thrown.

short_name()

char theplu::yat::utility::Option::short_name ( void  ) const

inherited

Returns

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

validate()

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()).

value() [1/2]

std::string theplu::yat::utility::OptionArg< std::string >::value ( void  ) const

inlineinherited

Returns

value

value() [2/2]

void theplu::yat::utility::OptionArg< std::string >::value ( std::string  v )

inlineinherited

set value

Since

new in yat 0.5
