## Public Member Functions

void | ascii_dump () const
| Writes to `std::cerr` an ASCII representation of `*this`.
void | ascii_dump (std::ostream &s) const
| Writes to `s` an ASCII representation of `*this`.
void | print () const
| Prints `*this` to `std::cerr` using `operator<<`.
bool | implies (const Poly_Con_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_Con_Relation | nothing ()

static Poly_Con_Relation | is_disjoint ()
| The polyhedron and the set of points satisfying the constraint are disjoint.
static Poly_Con_Relation | strictly_intersects ()
| The polyhedron intersects the set of points satisfying the constraint, but it is not included in it.
static Poly_Con_Relation | is_included ()
| The polyhedron is included in the set of points satisfying the constraint.
static Poly_Con_Relation | saturates ()
| The polyhedron is included in the set of points saturating the constraint.
