public abstract static class IloCplex.ProbingCallback
extends IloCplex.MIPCallback

An instance of the class ProbingCallback represents a user-written callback in an application that uses an instance of IloCplex to solve a MIP (mixed integer programming problem). This class offers a method to check on the progress of the cuts.

The methods of this class are protected for use in deriving a user-written callback class and in implementing the main method in it.

If an attempt is made to access information not available to an instance of this class, an exception is thrown.
