Detailed Description

Pack a set of values bitwise into a stream.

This helper can be used to pack a set of values into 32-bit words and write them to a stream. The number of bits taken by each value is configurable.

STREAM should support output (operator<<) with uint32_t (satisfied by a ROOT TBuffer).

template<class STREAM >

CxxUtils::BitPacker< STREAM >::BitPacker	(	uint8_t	nbits,
		STREAM &	stream
	)			`[inline]`

Constructor.

Parameters:

	nbits	Number of bits per item to use in the packed representation.
	stream	Output stream object.

template<class STREAM >

CxxUtils::BitPacker< STREAM >::~BitPacker ( ) [inline]

Destructor.

This may flush buffered data to the output stream.

template<class STREAM >

void CxxUtils::BitPacker< STREAM >::pack ( uint32_t dat ) [inline]

Pack one value to the stream.

Parameters:

x

The value to pack. The upper bits should all be clear.
