Binary Outfile Class.

Member Enumeration Documentation

enum itpp::bfstream_base::endian [inherited]

Definition of the endian data type.

The Endianness defines the order in which multibyte numbers are stored in the file. The two orders are called "Little Endian" (l_endian ) and "Big Endian" (b_endian ).

"Little Endian" means that the low-order byte of the number is stored at the lowest address (i.e. the little end comes first). "Big Endian" means that the high-order byte of the number is stored in memory at the lowest address (i.e. the big end comes first)

Constructor & Destructor Documentation

itpp::bofstream::bofstream	(	const std::string &	name,
		endian	e = b_endian
	)

Class constructor that opens a file and sets the endianity.

Parameters:

	name	The name of the file to open
	e	Defines the endianity of the class. Possible values are l_endian for "Little Endian" or b_endian for "Big Endian". The default value is b_endian.

Member Function Documentation

endian itpp::bfstream_base::get_native_endianity

(

)

const [inline, inherited]

Returns the native endianity for this computer architecture.

Intel processors use "Little Endian" byte ordering while e.g. Motorola processors use "Big Endian" byte ordering.

void itpp::bofstream::open	(	const std::string &	name,
		endian	e = b_endian
	)

Open a file for writing and set the endianity.

Parameters:

	name	The name of the file to open
	e	Defines the endianity of the class (default value is b_endian )
