| Constructors, Assignment and Destructor | |
| int | ppl_new_Generator (ppl_Generator_t *pg, ppl_const_Linear_Expression_t le, enum ppl_enum_Generator_Type t, ppl_const_Coefficient_t d) | 
| Creates a new generator of direction leand typet. If the generator to be created is a point or a closure point, the divisordis applied tole. For other types of generatorsdis simply disregarded. A handle for the new generator is written at addresspg. The space dimension of the new generator is equal to the space dimension ofle. | |
| int | ppl_new_Generator_zero_dim_point (ppl_Generator_t *pg) | 
| Creates the point that is the origin of the zero-dimensional space  . Writes a handle for the new generator at address pg. | |
| int | ppl_new_Generator_zero_dim_closure_point (ppl_Generator_t *pg) | 
| Creates, as a closure point, the point that is the origin of the zero-dimensional space  . Writes a handle for the new generator at address pg. | |
| int | ppl_new_Generator_from_Generator (ppl_Generator_t *pg, ppl_const_Generator_t g) | 
| Builds a generator that is a copy of g; writes a handle for the newly created generator at addresspg. | |
| int | ppl_assign_Generator_from_Generator (ppl_Generator_t dst, ppl_const_Generator_t src) | 
| Assigns a copy of the generator srctodst. | |
| int | ppl_delete_Generator (ppl_const_Generator_t g) | 
| Invalidates the handle g:this makes sure the corresponding resources will eventually be released. | |
| Functions that Do Not Modify the Generator | |
| int | ppl_Generator_space_dimension (ppl_const_Generator_t g, ppl_dimension_type *m) | 
| Writes to mthe space dimension ofg. | |
| int | ppl_Generator_type (ppl_const_Generator_t g) | 
| Returns the type of generator g. | |
| int | ppl_Generator_coefficient (ppl_const_Generator_t g, ppl_dimension_type var, ppl_Coefficient_t n) | 
| Copies into nthe coefficient of variablevarin generatorg. | |
| int | ppl_Generator_divisor (ppl_const_Generator_t g, ppl_Coefficient_t n) | 
| If gis a point or a closure point assigns its divisor ton. | |
| int | ppl_Generator_OK (ppl_const_Generator_t g) | 
| Returns a positive integer if gis well formed, i.e., if it satisfies all its implementation invariants; returns 0 and perhaps makes some noise ifgis broken. Useful for debugging purposes. | |
| Input/Output Functions | |
| int | ppl_io_print_Generator (ppl_const_Generator_t x) | 
| Prints xtostdout. | |
| int | ppl_io_fprint_Generator (FILE *stream, ppl_const_Generator_t x) | 
| Prints xto the given outputstream. | |
| int | ppl_io_asprint_Generator (char **strp, ppl_const_Generator_t x) | 
| Prints xto a malloc-allocated string, a pointer to which is returned viastrp. | |
| int | ppl_Generator_ascii_dump (ppl_const_Generator_t x, FILE *stream) | 
| Dumps an ascii representation of xonstream. | |
| int | ppl_Generator_ascii_load (ppl_Generator_t x, FILE *stream) | 
| Loads an ascii representation of xfromstream. | |
