Constructors and initialization

forceinline Gecode::IntVar::IntVar (void) IntVar void Default constructor. forceinline Gecode::IntVar::IntVar (const IntVar &y) IntVar const IntVar & y Initialize from integer variable y. forceinline Gecode::IntVar::IntVar (const Int::IntView &y) IntVar const Int::IntView & y Initialize from integer view y. GECODE_INT_EXPORT GECODE_INT_EXPORT Gecode::IntVar::IntVar (Space &home, int min, int max) IntVar Space & home int min int max 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::Int::Limits, an exception of type Gecode::Int::OutOfLimits is thrown. GECODE_INT_EXPORT GECODE_INT_EXPORT Gecode::IntVar::IntVar (Space &home, const IntSet &d) IntVar Space & home const IntSet & d 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::Int::Limits, an exception of type Gecode::Int::OutOfLimits is thrown.

Value access

int forceinline int Gecode::IntVar::min (void) const min void Return minimum of domain. int forceinline int Gecode::IntVar::max (void) const max void Return maximum of domain. int forceinline int Gecode::IntVar::med (void) const med void Return median of domain (greatest element not greater than the median) int forceinline int Gecode::IntVar::val (void) const val void Return assigned value. Throws an exception of type Int::ValOfUnassignedVar if variable is not yet assigned. unsigned int forceinline unsigned int Gecode::IntVar::size (void) const size void Return size (cardinality) of domain. unsigned int forceinline unsigned int Gecode::IntVar::width (void) const width void Return width of domain (distance between maximum and minimum) unsigned int forceinline unsigned int Gecode::IntVar::regret_min (void) const regret_min void Return regret of domain minimum (distance to next larger value) unsigned int forceinline unsigned int Gecode::IntVar::regret_max (void) const regret_max void Return regret of domain maximum (distance to next smaller value)

Domain tests

bool forceinline bool Gecode::IntVar::range (void) const range void Test whether domain is a range. bool forceinline bool Gecode::IntVar::in (int n) const in int n Test whether n is contained in domain. friend class friend class IntVarArray IntVarArray friend class friend class IntVarArgs IntVarArgs void forceinline void Gecode::IntVar::_init (Space &home, int min, int max) _init Space & home int min int max Initialize variable with range domain. The variable is created with a domain ranging from min to max. No exceptions are thrown. void forceinline void Gecode::IntVar::_init (Space &home, const IntSet &d) _init Space & home const IntSet & d Initialize variable with arbitrary domain. The variable is created with a domain described by d. No exceptions are thrown. class Char class Traits std::basic_ostream< Char, Traits > & std::basic_ostream< Char, Traits > & operator<< (std::basic_ostream< Char, Traits > &os, const IntVar &x) operator<< std::basic_ostream< Char, Traits > & os const IntVar & x Print integer variable x.
