static long ZCLUtils::bytesAsSigned	(	const byte	array[],
		const int	length
	)		[inline, static]

Return a signed value corresponding to an array of bytes.

Parameters:

array	the signed value as an array of bytes.
length	the array size.

Returns:

the signed value;

static long long ZCLUtils::bytesAsSigned64bits	(	const byte	array[],
		const int	length
	)		[inline, static]

Return a unsigned value corresponding to an array of bytes.

Only for the unsigned value on 5 bytes (40bits) and more.

Parameters:

array	the unsigned value as an array of bytes.
length	the array size.

Returns:

the unsigned value;

static unsigned long ZCLUtils::bytesAsUnsigned	(	const byte	array[],

Parameters:

array	the unsigned value as array of bytes.
length	the array size.

Returns:

the unsigned value;

static unsigned long long ZCLUtils::bytesAsUnsigned64bits	(	const byte	array[],
		const int	length
	)		[inline, static]

Return a unsigned value corresponding to an array of bytes.

Only for the unsigned value on 5 bytes (40bits) and more.

Parameters:

array	the unsigned value as array of bytes.

	)		[inline, static]

Fill a buffer of 1 to 8 bytes corresponding to the signed value.

b[0] = LSB, b[1] = ..., b[2] = ..., b[7] = MSB

Parameters:

buffer	the buffer to be written
value	the signed value.
length	the length in byte of signed value.

Returns:

the number of bytes written in the buffer.

static int ZCLUtils::signedAsBytes	(	byte *	buffer,
		long	value,
		int	length
	)		[inline, static]

Fill a buffer of 1 to 4 bytes corresponding to the signed value.

b[0] = LSB, b[1] = ..., b[2] = ..., b[3] = MSB

Parameters:

buffer	the buffer to be written
value	the signed value.
length	the length in byte of signed value.
