List of all members.

Classes
struct	Type
	Data type for storing VLI. More...
Public Member Functions
	VLI (int possibilities, int exponentAddition)
	Only initializes the settings.
int	bitsForLevel (int level) const
	Gets the number of bits needed to encode the residues of numbers at a given level.
Type	toVLI (int value) const
	Converts from signed integer to VLI.
int	fromVLI (int level, int data) const
	Converts from VLI to signed integer.
Public Attributes
const int	expAdd
	2^expAdd is the number of possibilities on the first level (level 0)
const int	maxLevel
	The highest possible level (in this settings).
const int	maxLevel_Bits
	The number of bits needed to encode residues in the highest level.
Private Member Functions
int	getBase (int level) const
	Returns the lowest number of a level (works with non-negative integers only).
Static Private Member Functions
static int	toPositive (int value)
	Simple routine converting from all integers to non-negative integers (interleaving).
static int	fromPositive (int value)
	Simple converting routine, opposite to toPositive.
static int	getLevel (int posValue, int expAdd)
	Returns the level of a non-negative integer depending on the setting of expAdd.
