Return numBits bits beginning at index as low-order return bits.
Declared in <bdlc_bitarray.h>
uint64_t
bits(
std::size_t index,
std::size_t numBits) const;Return the specified numBits beginning at the specified index in this array as the low-order bits of the returned value. The behavior is undefined unless numBits <= sizeof(uint64_t) * CHAR_BIT and index + numBits <= length().
