addDefaultArgument() [1/3]

void modelspace::ArgParser::addDefaultArgument	(	const std::string &	name,
		const std::string &	val
	)

Function to add a default argument that can be overridden from the cmd line.

Parameters

name	The name of the argument to add
val	The default value

addDefaultArgument() [2/3]

void modelspace::ArgParser::addDefaultArgument	(	const std::string &	name,
		double	val
	)

Function to add a default argument that can be overridden from the cmd line.

Parameters

name	The name of the argument to add
val	The default value

addDefaultArgument() [3/3]

void modelspace::ArgParser::addDefaultArgument	(	const std::string &	name,
		int	val
	)

Function to add a default argument that can be overridden from the cmd line.

Parameters

name	The name of the argument to add
val	The default value

get() [1/3]

int modelspace::ArgParser::get	(	const std::string &	name,
		double &	val
	)

Function to get the string value of an arg as a double.

Parameters

name	The arg to get
val	The returned value

Returns

		std::string &	val
	)

Function to get the string value of an arg.

Parameters

name	The arg to get
val	The returned value

Returns

The arg as a string value. Empty string if arg does not exist

operator()()
