C++ Reference: class IntVar

Note: This documentation is automatically generated.

The class IntVar is a subset of IntExpr. In addition to the IntExpr protocol, it offers persistence, removing values from the domains, and a finer model for events.

Method
Accept	Return type: void Arguments: ModelVisitor* const visitor Accepts the given visitor.
Contains	Return type: virtual bool Arguments: int64_t v This method returns whether the value 'v' is in the domain of the variable.
index	Return type: int Returns the index of the variable.
IntVar	Return type: explicit Arguments: Solver* const s
IntVar	Arguments: Solver* const s, const std::string& name
~IntVar
IsDifferent	Return type: virtual IntVar* Arguments: int64_t constant
IsEqual	Return type: virtual IntVar* Arguments: int64_t constant IsEqual
IsGreaterOrEqual	Return type: virtual IntVar* Arguments: int64_t constant
IsLessOrEqual	Return type: virtual IntVar* Arguments: int64_t constant
IsVar	Return type: bool
MakeDomainIterator	Return type: virtual IntVarIterator* Arguments: bool reversible Creates a domain iterator. When 'reversible' is false, the returned object is created on the normal C++ heap and the solver does NOT take ownership of the object.
MakeHoleIterator	Return type: virtual IntVarIterator* Arguments: bool reversible Creates a hole iterator. When 'reversible' is false, the returned object is created on the normal C++ heap and the solver does NOT take ownership of the object.
OldMax	Return type: virtual int64_t Returns the previous max.
OldMin	Return type: virtual int64_t Returns the previous min.
RemoveInterval	Return type: virtual void Arguments: int64_t l, int64_t u This method removes the interval 'l' .. 'u' from the domain of the variable. It assumes that 'l' <= 'u'.
RemoveValue	Return type: virtual void Arguments: int64_t v This method removes the value 'v' from the domain of the variable.
RemoveValues	Return type: virtual void Arguments: const std::vector<int64_t>& values This method remove the values from the domain of the variable.
SetValues	Return type: virtual void Arguments: const std::vector<int64_t>& values This method intersects the current domain with the values in the array.
Size	Return type: virtual uint64_t This method returns the number of values in the domain of the variable.
Value	Return type: virtual int64_t This method returns the value of the variable. This method checks before that the variable is bound.
Var	Return type: IntVar*
VarType	Return type: virtual int
WhenBound	Return type: virtual void Arguments: Demon* d This method attaches a demon that will be awakened when the variable is bound.
WhenBound	Return type: void Arguments: Solver::Closure closure This method attaches a closure that will be awakened when the variable is bound.
WhenBound	Return type: void Arguments: Solver::Action action This method attaches an action that will be awakened when the variable is bound.
WhenDomain	Return type: virtual void Arguments: Demon* d This method attaches a demon that will watch any domain modification of the domain of the variable.
WhenDomain	Return type: void Arguments: Solver::Closure closure This method attaches a closure that will watch any domain modification of the domain of the variable.
WhenDomain	Return type: void Arguments: Solver::Action action This method attaches an action that will watch any domain modification of the domain of the variable.
