Detailed Description

Base class for parameters.

Constructor & Destructor Documentation

template<typename T >

dolfin::Parameter::Parameter ( std::string  key, T  x  )

inline

Create parameter for given key and value

Parameters

key	(std::string)
x	(T)

Parameter::Parameter	(	std::string	key,
		const char *	x
	)

Create parameter for given key and value. This verison (const char*) is necessary to have the parameter treated as a string rather than char* being cast as bool.

Parameters

key	(std::string)
x	(const char*))

Parameter::Parameter	(	std::string	key,
		Type	ptype
	)

Create an unset parameter (type is specified, value is unknown)

Parameters

key	(std::string)
ptype	(Type))

template<typename T >

dolfin::Parameter::Parameter ( std::string  key, T  min, T  max  )

inline

Create and unset numerical parameter with specified (min, max) range
