isSet()

template<typename BITMASK1 , typename BITMASK2 >

bool zserio::builtin::isSet	(	BITMASK1	bitmaskValue,
		BITMASK2	requiredMask
	)

Checks whether the requiredMask is set within the bitmaskValue.

This method implements zserio built-in operator isset.

Parameters

bitmaskValue	Bitmask value to check.
requiredMask	Mask to use.

Returns

True when the requiredMask is set within the bitmaskValue, false otherwise.

numBits()

uint8_t zserio::builtin::numBits

(

uint64_t

numValues

)

Gets the minimum number of bits required to encode numValues different values.

This method implements Zserio built-in operator numbits.

Note: Please note that this method returns 0 if numValues is zero.

Examples: numbits(0) = 0 numbits(1) = 1 numbits(2) = 1 numbits(3) = 2 numbits(4) = 2 numbits(8) = 3 numbits(16) = 4

Parameters

numValues

The number of different values from which to calculate number of bits.

Returns

Number of bis required to encode numValues different values.
