The relation between a polyhedron and a generator. More...

`#include <ppl.hh>`

## 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_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.
