Class IlcIntToIntExpFunctionI

This class is the implementation class for IlcIntToIntExpFunction, the class of the object that makes the association between an integer value and a constrained integer variable or expression.

The virtual member function getValue returns the constrained variable or expression associated with a given value. To define an association class, you have to derive this class, and overload the getValue virtual member function.

The following constraints and expressions use this kind of indirection: IlcSum, IlcMin, IlcMax, and IlcUnion.

This constructor creates an implementation object.

As this class is to be subclassed, a virtual destructor is provided

This member function must return the constrained variable or expression associated with the integer element e.
