Value access | |
int | min (void) const |
Return minimum of domain. | |

Return maximum of domain. | |
int | med (void) const |
Return median of domain. | |
int | val (void) const |
Return assigned value (only if assigned). | |
unsigned int | size (void) const |
Return size (cardinality) of domain. | |
unsigned int | width (void) const |
Return width of domain (distance between maximum and minimum). | |
unsigned int | regret_min (void) const |
Return regret of domain minimum (distance to next larger value). | |
unsigned int | regret_max (void) const |
Return regret of domain maximum (distance to next smaller value). | |
Domain tests | |
bool | range (void) const |
Test whether domain is a range. | |
bool | assigned (void) const |
Test whether view is assigned. | |
bool | in (int n) const |
Test whether n is contained in domain. | |
bool | in (double n) const |
Test whether n is contained in domain. | |
Domain update by value | |
ModEvent | lq (Space *home, int n) |
Restrict domain values to be less or equal than n. | |
ModEvent | lq (Space *home, double n) |
Restrict domain values to be less or equal than n. | |
ModEvent | le (Space *home, int n) |
Restrict domain values to be less than n. | |
ModEvent | le (Space *home, double n) |
Restrict domain values to be less than n. | |
ModEvent | gq (Space *home, int n) |
Restrict domain values to be greater or equal than n. | |
ModEvent | gq (Space *home, double n) |
Restrict domain values to be greater or equal than n. | |
ModEvent | gr (Space *home, int n) |
Restrict domain values to be greater than n. | |
ModEvent | gr (Space *home, double n) |
Restrict domain values to be greater than n. | |
ModEvent | nq (Space *home, int n) |
Restrict domain values to be different from n. | |
ModEvent | nq (Space *home, double n) |
Restrict domain values to be different from n. | |
ModEvent | eq (Space *home, int n) |
Restrict domain values to be equal to n. | |
ModEvent | eq (Space *home, double n) |
Restrict domain values to be equal to n. | |
Domain update by range iterator | |
template<class I> | |
ModEvent | narrow (Space *home, I &i) |
Replace domain by range sequence described by i. | |
template<class I> | |
ModEvent | inter (Space *home, I &i) |
Intersect domain with range sequence described by i. | |
template<class I> | |
ModEvent | minus (Space *home, I &i) |
Remove from domain the range sequence described by i. | |
Cloning | |
void | update (Space *home, bool share, IntView &x) |
Update this view to be a clone of view x. | |
