Public Types
enum	Type {   BIT, SCHAR, UCHAR, SHORT,   USHORT, INT, UINT, LONG,   ULONG, FLOAT, DOUBLE, UNKNOWN_TYPE }
	An enum for the supported types.

Public Member Functions
	NumericType (Type t=UNKNOWN_TYPE)
	constructor, defaulting to unknown type
	NumericType (const std::string &number_format, const std::size_t size_in_bytes)
	A constructor to work from named types a la Interfile. More...
bool	operator== (NumericType type) const
	comparison operator
bool	operator!= (NumericType type) const
std::size_t	size_in_bytes () const
	as reported by sizeof(), so it is really size_in_sizeof_char
std::size_t	size_in_bits () const
bool	signed_type () const
	returns true for all built-in types, except unsigned types
bool	integer_type () const
	returns true for all built-in types, except float and double
void	get_Interfile_info (std::string &number_format, std::size_t &size_in_bytes) const
	returns the names and size a la Interfile. see NumericType(const string&,const std::size_t)

Public Attributes
Type	id
	stores the current type

Detailed Description

provides names for some numeric types and methods for finding their properties.

Warning

CHAR itself is missing (there's only signed and unsigned versions). This is because this class is only used where you have to know if the type is signed.

Constructor & Destructor Documentation

NumericType()

stir::NumericType::NumericType	(	const std::string &	number_format,
		const std::size_t	size_in_bytes
	)

A constructor to work from named types a la Interfile.

Possible values for number_format are bit, signed integer, unsigned integer, float Exact types are determined via the size_in_bytes parameter.
