Detailed Description

Binary data utilities.

These functions and macros are to be used for manipulating binary data.

Classes
class	CRCException
	This is thrown when there is an error processing a CRC. More...
class	CRCParam
	Encapsulate parameters for CRC computation. More...
Functions
template<class T>
void	twiddle (T &p) throw ()
	Reverse bytes.
template<class T>
T	intelToHost (const T &p) throw ()
	Converts Intel little-endian to host byte order, const version.
template<class T>
T	hostToIntel (const T &p) throw ()
	Converts host byte order to Intel little-endian, const version.
template<class T>
T	netToHost (const T &p) throw ()
	Converts host byte order to network order, const version.
template<class T>
T	hostToNet (const T &p) throw ()
	Converts network byte order to host order, const version.
template<class T>
T	decodeVar (std::string &str, std::string::size_type pos=std::string::npos)
	Remove (optinally) the item specified from the string and convert it from network byte order to host byte order.
template<class T>
std::string	encodeVar (const T &v)
	Add the network ordered binary representation of a var to the the given string.
unsigned long	reflect (unsigned long crc, int bitnum)
	Reflects the lower bitnum bits of crc.
unsigned long	computeCRC (const unsigned char *data, unsigned long len, const CRCParam &params)
	Compute CRC (suitable for polynomial orders from 1 to 32).
template<class X>
X	xorChecksum (const std::string &str) throw (gpstk::InvalidParameter)
	Calculate an Exclusive-OR Checksum on the string /a str.
Variables
const CRCParam	CRCCCITT (16, 0x1021, 0xffff, 0, true, false, false)
const CRCParam	CRC16 (16, 0x8005, 0, 0, true, true, true)
const CRCParam	CRC32 (32, 0x4c11db7, 0xffffffff, 0xffffffff, true, true, true)
const CRCParam	CRC24Q (24, 0x823ba9, 0, 0xffffffff, true, false, false)
