public abstract static class IloCplex.FlowMIRCutCallback
extends IloCplex.MIPCallback

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

The constructor and 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.
