IloModelingAssistance (CPLEX Java API Reference Manual)

java.lang.Object
- ilog.cplex.IloModelingAssistance

```
public final class IloModelingAssistance
extends java.lang.Object
```
A class for modeling assistance.
This class provides a namespace for the modeling assistance callback interface (see IloModelingAssistance.Callback). For each invocation of the callback, a modeling information ID and warning string are provided (see the IloModelingAssistance.Callback.invoke(int, java.lang.String) method).

This class also exposes modeling information IDs as defined by the CPLEX Callable Library. These constants define symbolic names for the integer modeling information IDs returned by the Callable Library (C API). The names to which the modeling information IDs are assigned are the same names used in the Callable Library except that the leading CPXMI characters have been left out. For example, the IloModelingAssistance.BIGM_COEF constant corresponds with the CPXMI_BIGM_COEF macro in the Callable Library. The modeling information IDs are accessible through the modeling assistance callback. These symbolic names can be used to test if a particular modeling issue has been detected.
