Detailed Description

template<class STREAM>
class CxxUtils::BitUnpacker< STREAM >

Helper to unpack a set of values bitwise from a stream.

This helper can be used to unpack a set of values from a stream and return them as a set of 32-bit words. The number of bits taken by each value is configurable.

STREAM should support input (operator>>) with uint32_t (satisfied by a ROOT TBuffer).
