Detailed Description

Class BitVec defines a bit-vector as an array of BitVecType.

Necessary for space-filling curve. Bit are numbered from O; i.e. The MSB of BitVec[0] is bit 0 and the LSB of BitVec[Dim-1] is bit NBit-1 where NBit=Sizeof(BitVecType)*Dim. Operations on the bit vector include testing/setting and toggleing a set of bits corresponding to a digit and isolating the bits. This class has been modified to have a fix maxlen of the bitvector so that it does not need dynamic allocations.

Constructor & Destructor Documentation

BitVec::BitVec (  const int    len ) 
 

Constructor BitVec creates a bit vector of length "len" as an of BitVecType.

The bit vector is initialized to 0.

Member Function Documentation

void BitVec::SwapBit (  const int    loc1,
const int    loc2
) 
 

swaps the bits at locations "loc1" and "loc2".

Remember that the most significant bit is numbered 0.
