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.
