Public Member Functions | |
bool | implies (const Poly_Gen_Relation &y) const |
True if and only if *this implies y . | |
bool | OK () const |
Checks if all the invariants are satisfied. | |
Static Public Member Functions | |
static Poly_Gen_Relation | nothing () |
The assertion that says nothing. | |
static Poly_Gen_Relation | subsumes () |
Adding the generator would not change the polyhedron. | |
Friends | |
bool | operator== (const Poly_Gen_Relation &x, const Poly_Gen_Relation &y) |
True if and only if x and y are logically equivalent. | |
bool | operator!= (const Poly_Gen_Relation &x, const Poly_Gen_Relation &y) |
True if and only if x and y are not logically equivalent. | |
Poly_Gen_Relation | operator && (const Poly_Gen_Relation &x, const Poly_Gen_Relation &y) |
Yields the logical conjunction of x and y . | |
Poly_Gen_Relation | operator- (const Poly_Gen_Relation &x, const Poly_Gen_Relation &y) |
Yields the assertion with all the conjuncts of x that are not in y . | |

Output operator. |
This class implements conjunctions of assertions on the relation between a polyhedron and a generator.
