Constructor & Destructor Documentation

Linear()

MaterialPropertyLib::Linear::Linear	(	std::string	name,
		PropertyDataType const &	property_reference_value,
		std::vector< IndependentVariable > const &	vs )

This constructor accepts single values of double data type defined in the PropertyDataType definition and sets the protected attribute value_ of the base class Property to that value.
