void	clear (void)
	Returns self to an 'undefined' state where defined() returns 'false'. 'undefined' essentially means 'no data available' / 'N/A' or 'null' as used by some database systems. Note that an 'undefined' variant can still have a type.
bool	defined (void) const
	Returns true if a value has been assigned and the object is in a 'defined' date. In other words it is 'not-null'. More...
