Constructors, Assignment and Destructor | |
int | ppl_new_Grid_Generator (ppl_Grid_Generator_t *pg, ppl_const_Linear_Expression_t le, enum ppl_enum_Grid_Generator_Type t, ppl_const_Coefficient_t d) |
Creates a new grid generator of direction le and type t . If the grid generator to be created is a point or a parameter, the divisor d is applied to le . If it is a line, d is simply disregarded. A handle for the new grid generator is written at address pg . The space dimension of the new grid generator is equal to the space dimension of le . | |
int | ppl_new_Grid_Generator_zero_dim_point (ppl_Grid_Generator_t *pg) |
Creates the point that is the origin of the zero-dimensional space ![]() pg . | |
int | ppl_new_Grid_Generator_from_Grid_Generator (ppl_Grid_Generator_t *pg, ppl_const_Grid_Generator_t g) |
Builds a grid generator that is a copy of g ; writes a handle for the newly created grid generator at address pg . | |
int | ppl_assign_Grid_Generator_from_Grid_Generator (ppl_Grid_Generator_t dst, ppl_const_Grid_Generator_t src) |
Assigns a copy of the grid generator src to dst . | |
int | ppl_delete_Grid_Generator (ppl_const_Grid_Generator_t g) |
Invalidates the handle g: this makes sure the corresponding resources will eventually be released. | |
Functions that Do Not Modify the Grid Generator | |
int | ppl_Grid_Generator_space_dimension (ppl_const_Grid_Generator_t g, ppl_dimension_type *m) |
Writes to m the space dimension of g . | |
int | ppl_Grid_Generator_type (ppl_const_Grid_Generator_t g) |
Returns the type of grid generator g . | |
int | ppl_Grid_Generator_coefficient (ppl_const_Grid_Generator_t g, ppl_dimension_type var, ppl_Coefficient_t n) |
Copies into n the coefficient of variable var in grid generator g . | |
int | ppl_Grid_Generator_divisor (ppl_const_Grid_Generator_t g, ppl_Coefficient_t n) |
If g is a point or a parameter assigns its divisor to n . | |
int | ppl_Grid_Generator_OK (ppl_const_Grid_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_Grid_Generator (ppl_const_Grid_Generator_t x) |
Prints x to stdout . | |
int | ppl_io_fprint_Grid_Generator (FILE *stream, ppl_const_Grid_Generator_t x) |
Prints x to the given output stream . | |
int | ppl_io_asprint_Grid_Generator (char **strp, ppl_const_Grid_Generator_t x) |
Prints x to a malloc-allocated string, a pointer to which is returned via strp . | |
int | ppl_Grid_Generator_ascii_dump (ppl_const_Grid_Generator_t x, FILE *stream) |
Dumps an ascii representation of x on stream . | |
int | ppl_Grid_Generator_ascii_load (ppl_Grid_Generator_t x, FILE *stream) |
Loads an ascii representation of x from stream . | |
