const_iterator begin (    )  const [inline]

Bit manipulation function for possible use in optimization efficiently pulls out continuous blocks of bits, from lsb to msb inclusive least significant bits start at index 0, so msb >= lsb if any bits with index >= 8*numBytes are asked for they will be zeroes static long long bytesToBits(unsigned char * byteArray, size_t numBytes, size_t lsb, size_t msb) { linbox_check(msb >= lsb); size_t lsbi = lsb >> 3; size_t msbi = msb >> 3; if (msbi == lsbi) if (msbi >= numBytes) return 0; else return (byteArray[lsbi] >> (lsb & 7)) & ((1 << (msb - lsb + 1)) - 1); long long result = (msbi < numBytes) ? (byteArray[msbi] & ((1 << ((msb & 7)+1)) - 1)) : 0; for (size_t i=msbi-1; i>lsbi; i--) { result <<= 8; result |= (i < numBytes) ? byteArray[i] : 0; } result <<= 8 - (lsb & 7); result |= (lsbi < numBytes) ? (byteArray[lsbi] >> (lsb & 7)) : 0; return result; }
