Typedef IlcChooseAnyIndex

This C++ type represents a pointer to a function that takes an array of constrained enumerated variables and returns an integer.

In its search primitives for finding solutions, Solver lets you set parameters for choosing the order in which constrained variables are bound. You do so by means of choice functions called criteria.

The choice functions for constrained enumerated variables (that is, instances of IlcAnyExp or its subclasses) should have a signature of this type.
