◆ get_string()

std::string jau::get_string	(	const uint8_t *	buffer,
		nsize_t const	buffer_len,
		nsize_t const	max_len
	)

noexcept

Returns a C++ String taken from buffer with maximum length of min(max_len, max_len).

The maximum length only delimits the string length and does not contain the EOS null byte. An EOS null byte will will be added.

The source string within buffer is not required to contain an EOS null byte;

◆ trimInPlace()

void jau::trimInPlace ( std::string & s )

noexcept

trim in place

◆ split_string()

std::vector< std::string > jau::split_string	(	const std::string &	str,

◆ hexStringBytes() [1/2]

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.

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

Examples: test_basictypeconv.cpp.

◆ bytesHexString() [1/2]

std::string jau::bytesHexString	(	const void *	data,
		const nsize_t	offset,
		const nsize_t	length,
		const bool	lsbFirst,
		const bool	lowerCase = `true`
	)

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.

Parameters

data	pointer to the first byte to print, less offset
offset	offset to bytes 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, otherwise capital letters are being used.

Returns: the hex-string representation of the data

Examples: test_basictypeconv.cpp.
