Constructors and initialization | |
| IntVar (void) | |
| Default constructor. | |
| IntVar (const IntVar &x) | |
| Initialize from integer variable x. | |
| IntVar (const Int::IntView &x) | |
| Initialize from integer view x. | |
| IntVar (Space *home, int min, int max) | |
| Initialize variable with range domain. | |
| IntVar (Space *home, const IntSet &d) | |
| Initialize variable with arbitrary domain. | |
| void | init (Space *home, int min, int max) |
| Initialize variable with range domain. | |
| void | init (Space *home, const IntSet &d) |
| Initialize variable with arbitrary domain. | |
Variable implementation access | |
| Int::IntVarImp * | variable (void) const |
| Return integer variable implementation. | |
Value access | |
| int | min (void) const |
| Return minimum of domain. | |
| int | max (void) const |
| 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 | degree (void) const |
| Return degree (number of subscribed propagators). | |
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. | |
Cloning | |
| void | update (Space *home, bool share, IntVar &x) |
| Update this variable to be a clone of variable x. | |
Protected Attributes | |

Initialize variable with range domain.
The variable is created with a domain ranging from min to max. The following exceptions might be thrown:
- If min is greater than max, an exception of type Gecode::Int::VariableEmptyDomain is thrown.
- If min or max exceed the limits for integers as defined in Gecode::Limits::Int, an exception of type Gecode::Int::VariableOutOfDomain is thrown.
Initialize variable with arbitrary domain.
The variable is created with a domain described by d. The following exceptions might be thrown:
- If d is empty, an exception of type Gecode::Int::VariableEmptyDomain is thrown.
- If d contains values that exceed the limits for integers as defined in Gecode::Limits::Int, an exception of type Gecode::Int::VariableOutOfDomain is thrown.
