C++ Reference: class IntExpr

This documentation is automatically generated.

The class IntExpr is the base of all integer expressions in constraint programming. It contains the basic protocol for an expression:
   - setting and modifying its bound
   - querying if it is bound
   - listening to events modifying its bounds
   - casting it into a variable (instance of IntVar)

Method
Accept	Return type: virtual void Arguments: ModelVisitor* const visitor Accepts the given visitor.
Bound	Return type: virtual bool Returns true if the min and the max of the expression are equal.
IntExpr	Return type: explicit Arguments: Solver* const s
~IntExpr
IsVar	Return type: virtual bool Returns true if the expression is indeed a variable.
Max	Return type: virtual int64
Min	Return type: virtual int64
Range	Return type: virtual void Arguments: int64* l, int64* u By default calls Min() and Max(), but can be redefined when Min and Max code can be factorized.
SetMax	Return type: virtual void Arguments: int64 m
SetMin	Return type: virtual void Arguments: int64 m
SetRange	Return type: virtual void Arguments: int64 l, int64 u This method sets both the min and the max of the expression.
SetValue	Return type: virtual void Arguments: int64 v This method sets the value of the expression.
Var	Return type: virtual IntVar* Creates a variable from the expression.
VarWithName	Return type: IntVar* Arguments: const std::string& name Creates a variable from the expression and set the name of the resulting var. If the expression is already a variable, then it will set the name of the expression, possibly overwriting it. This is just a shortcut to Var() followed by set_name().
WhenRange	Return type: virtual void Arguments: Demon* d Attach a demon that will watch the min or the max of the expression.
WhenRange	Return type: void Arguments: Solver::Closure closure Attach a demon that will watch the min or the max of the expression.
WhenRange	Return type: void Arguments: Solver::Action action Attach a demon that will watch the min or the max of the expression.
