Public Methods

Method	Description
Access ( int pos ) : bool
Add ( int current ) : void
Add ( int current, int prev ) : void	Adds an (ordered) item to the set
AssertEquality ( Bitmap _other ) : void
Build ( IEnumerable orderedList, int n, short b, IIEncoder32 coder = null ) : void	build methods
Build ( IList orderedList, short b, IIEncoder32 coder = null ) : void
Commit ( ) : void	Write the sequence to the bitmap. DiffSet always commit items.
DiffSet ( ) : System
DiffSet ( short B ) : System
ExtractFrom ( int start_index, int count, List output ) : int	Extract 'count' differences starting from 'start_index', it saves the output in 'output'. Returns the previous absolute value to start_index (start_index - 1), i.e. the reference
Load ( BinaryReader R ) : void
Rank1 ( int pos ) : int
Save ( BinaryWriter W ) : void
Select1 ( int rank ) : int	Returns the position of the rank-th enabled bit
Select1Difference ( int rank ) : int	Returns the difference between Select1(rank) - Select1(rank-1)
