using Utils::Buffer = typedef Byte*

Function Documentation

hexCharToByte()

Byte Utils::hexCharToByte ( char  x )

inline

Converts hexadecimal char to byte.

Parameters

x	input hexadecimal char

Returns

output byte

Exceptions

std::invalid_argument

Throws when input is not valid hexadecimal char

byteToHexChar()

char Utils::byteToHexChar ( Byte  x )

inline

Converts byte to hexadecimal char.

Parameters

x	input byte

Returns

output char

Exceptions

std::invalid_argument

Throws when input is not valid hexadecimal value

hexStringToBuffer() [1/2]

std::size_t Utils::hexStringToBuffer ( const char *  input, std::size_t  inputLength, Buffer  output, bool  stripZeroes = false  )

inline

Converts hexadecimal string to buffer.

Parameters

input	input hexadecimal c-string
inputLength	length of the input string
output	output buffer
stripZeroes	should input string be trimmed of leading zeroes

Returns

output buffer length

hexStringToBuffer() [2/2]

std::size_t Utils::hexStringToBuffer ( const char *  input, Buffer  output, bool  stripZeroes = false  )

inline

Converts hexadecimal null-terminated string to buffer.

Parameters

input	input hexadecimal null-terminated c-string
output	output buffer
stripZeroes	should input string be trimmed of leading zeroes

Returns

output buffer length

bufferToHexString()

std::size_t Utils::bufferToHexString ( Buffer  input, std::size_t  inputLength, char *  output, bool  nullTerminated = false  )

inline

Converts buffer to hexadecimal string.

Parameters

input	input buffer
inputLength	length of the input buffer
output	output hexadecimal c-string, padded to even length
nullTerminated	should string be null terminated, defaults to false

Returns

output c-string length (without null terminator)

intToBuffer()

std::size_t Utils::intToBuffer ( std::uint64_t  x, Buffer  output  )

inline

Converts integer to buffer.

Parameters

x	input integer
output	output buffer

Returns

output buffer length
