bool init(const Point &lower, const Point &upper, bool isClosed)
Specifies the upper and lower bounds for the maximal cells in this space.
SCell sCell(const SPreCell &c) const
From a signed cell, returns a signed cell lying into this Khalismky space.
SCell sTranslation(const SCell &p, const Vector &vec) const
Add the vector [vec] to [p].
SCell sPointel(Point p, Sign sign=POS) const
From the digital coordinates of a point in Zn, builds the corresponding pointel (cell of dimension 0)...
