Method	Description
AssignBit ( int bitmap, int i, bool x ) : int	Assign the (i+1)th bit to x. Overload using int as bitmap
GetBit ( List bitmap, int i ) : bool	Gets the (i+1)th bit. Overload using bytes.
GetBit ( List bitmap, long i ) : bool	Gets the (i+1)th bit.
GetBit ( int bitmap, int i ) : bool	Gets the (i+1)th bit. Overload using int as bitmap
Log2 ( int u ) : int	floor(Log2) of the specified u.
Log2 ( long u ) : int
Rank1 ( List bitmap, int start, int count, int bitpos ) : int
Rank1 ( uint bitmap, int bitpos ) : int	Returns Rank1(bitpos) at bitmap
ResetBit ( int bitmap, int i ) : int	Reset the (i+1)th bit. Overload using int as bitmap
ResetBit ( List bitmap, int i ) : void	Resets the (i+1)th bit. Overload using bytes.
ResetBit ( List bitmap, long i ) : void	Resets the (i+1)th bit.
Reverse ( int bitmap, int size ) : int	Reverse the first size bits inside the bitmap

Select1 ( uint bitmap, int rank ) : int	Select1 of rank
Select1 ( uint bitmap, int rank, int &rankout ) : int	Select of the (rank) th the specified bitmap, rank and rankout.
Select1BitArgs ( List bitmap, int start_bit, int max_count_bits, int rank ) : int	Select1 of rank, the bit sequences is bitmap. The search starts in start_bit, reviewing atmost max_count_bits.
SetBit ( int bitmap, int i ) : int	Enables the (i+1)th bit. Overload using int as bitmap
SetBit ( List bitmap, int i ) : void	Enalbes the (i+1)th bit.
SetBit ( List bitmap, long i ) : void	Enables the (i+1)th bit.
