size_t jau::hexStringBytes	(	std::vector< uint8_t > &	out,
		const std::string &	hexstr,
		const bool	lsbFirst,
		const bool	checkLeading0x )

noexcept

Converts a given hexadecimal string representation into a byte vector.

In case a non valid hexadecimal digit appears in the given string, conversion ends and fills the byte vector up until the violation.

If string is in MSB first (default w/ leading 0x) and platform jau::is_little_endian(), lsbFirst = false shall be passed.

In case hexstr contains an odd number of hex-nibbles, it will be interpreted as follows

0xf12 = 0x0f12 = { 0x12, 0x0f } - msb, 1st single low-nibble is most significant
12f = 0xf012 = { 0x12, 0xf0 } - lsb, last single high-nibble is most significant

Parameters

out	the byte vector sink
hexstr	the hexadecimal string representation
lsbFirst	low significant byte first
checkLeading0x	if true, checks for a leading `0x` and removes it, otherwise not.

Returns: the length of the matching byte vector

◆ from_hexstring()

uint64_t jau::from_hexstring	(	std::string const &	s,
		const bool	lsbFirst = !jau::is_little_endian(),
		const bool	checkLeading0x = true )

noexcept

Converts a given hexadecimal string representation into a uint64_t value according to hexStringBytes().

If string is in MSB first (default w/ leading 0x) and platform jau::is_little_endian(), lsbFirst = false shall be passed (default).

Parameters

s	the hexadecimal string representation
lsbFirst	low significant byte first
checkLeading0x	if true, checks for a leading `0x` and removes it, otherwise not.

Returns: the uint64_t value

noexcept

Produce a hexadecimal string representation of the given byte values.

If lsbFirst is true, orders LSB left -> MSB right, usual for byte streams. Result will not have a leading 0x.
Otherwise orders MSB left -> LSB right, usual for readable integer values. Result will have a leading 0x if !skipLeading0x (default).

Parameters

data	pointer to the first byte to print
length	number of bytes to print
lsbFirst	true having the least significant byte printed first (lowest addressed byte to highest), otherwise have the most significant byte printed first (highest addressed byte to lowest). A leading `0x` will be prepended if `lsbFirst == false`.
lowerCase	true to use lower case hex-chars (default), otherwise capital letters are being used.
skipLeading0x	false to add leading `0x` if !lsbFirst (default), true to not add (skip)..

Returns: the hex-string representation of the data
