Function Documentation

decDump()

QString decDump	(	unsigned char *	data,
		unsigned int	length )

hexdecDump()

QString hexdecDump	(	unsigned char *	data,
		unsigned int	length )

hexDump()

QString hexDump	(	unsigned char *	data,
		unsigned int	length )

Returns the hex or decimal dump for the given data.

Parameters

data	Pointer to the data bytes that should be dumped.
length	The length of the data array in bytes.

Returns

String with the dump of the data.

hexParse()

unsigned int hexParse	(	const QString	dump,
		unsigned char *	data,
		unsigned int	length )

Returns the hex dump for the given data.

Parameters

dump	The string with the hex dump of the data.
data	Pointer to the address where the data bytes should be saved.
length	The maximum length of the data array in bytes.

Returns

The length of the saved data.

stringToValue()

double stringToValue	(	const QString &	text,
		Unit	unit,
		bool *	ok = nullptr )

Converts string containing value and (prefix+)unit to double (Counterpart to valueToString).

Parameters

text	The text containing the value and its unit.
unit	The base unit of the value.
ok	Pointer to a success-flag, true on success, false on error.

Returns

Decoded value.

valueToString()

QString valueToString	(	double	value,
		Unit	unit,
		int	precision = -1 )

Converts double to string containing value and (prefix+)unit (Counterpart to stringToValue).

Parameters

value	The value in prefixless units.
unit	The unit for the value.
precision	Significant digits, 0 for integer, -1 for auto.

Returns

String with the value and unit.
