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 le and type t. If the generator to be created is a point or a closure point, the divisor d is applied to le. For other types of generators d is simply disregarded. A handle for the new generator is written at address pg. The space dimension of the new generator is equal to the space dimension of le. | |
| 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 address pg. | |
| int | ppl_assign_Generator_from_Generator (ppl_Generator_t dst, ppl_const_Generator_t src) |
Assigns a copy of the generator src to dst. | |
| 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 m the space dimension of g. | |
| 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 n the coefficient of variable var in generator g. | |
| int | ppl_Generator_divisor (ppl_const_Generator_t g, ppl_Coefficient_t n) |
If g is a point or a closure point assigns its divisor to n. | |
| int | ppl_Generator_OK (ppl_const_Generator_t g) |
Returns a positive integer if g is well formed, i.e., if it satisfies all its implementation invariants; returns 0 and perhaps makes some noise if g is broken. Useful for debugging purposes. | |
Input/Output Functions | |
| int | ppl_io_print_Generator (ppl_const_Generator_t x) |
Prints x to stdout. | |
| int | ppl_io_fprint_Generator (FILE *stream, ppl_const_Generator_t x) |
Prints x to the given output stream. | |
| int | ppl_io_asprint_Generator (char **strp, ppl_const_Generator_t x) |
Prints x to a malloc-allocated string, a pointer to which is returned via strp. | |
| int | ppl_Generator_ascii_dump (ppl_const_Generator_t x, FILE *stream) |
Dumps an ascii representation of x on stream. | |
| int | ppl_Generator_ascii_load (ppl_Generator_t x, FILE *stream) |
Loads an ascii representation of x from stream. | |
