A line, ray, point or closure point.
An object of the class Generator is one of the following:
| static Generator parma_polyhedra_library::Generator::closure_point | ( | Linear_Expression | e, | |
| Coefficient | d | |||
| ) | [inline, static] |
Returns the closure point at e / d.
| RuntimeErrorException | Thrown if d is zero. |
| static Generator parma_polyhedra_library::Generator::line | ( | Linear_Expression | e | ) | [inline, static] |
Returns the line of direction e.
| RuntimeErrorException | Thrown if the homogeneous part of e represents the origin of the vector space. |
| static Generator parma_polyhedra_library::Generator::point | ( | Linear_Expression | e, | |
| Coefficient | d | |||
| ) | [inline, static] |
Returns the point at e / d.
| RuntimeErrorException | Thrown if d is zero. |
| static Generator parma_polyhedra_library::Generator::ray | ( | Linear_Expression | e | ) | [inline, static] |
Returns the ray of direction e.
| RuntimeErrorException | Thrown if the homogeneous part of e represents the origin of the vector space. |
| Coefficient parma_polyhedra_library::Generator::divisor | ( | ) | [inline] |
If this is either a point or a closure point, returns its divisor.
| RuntimeErrorException | Thrown if this is neither a point nor a closure point. |
