Class IloCplex::DisjunctiveCutCallbackI

Definition file: ilcplex/ilocplexi.h

An instance of the class IloCplex::DisjunctiveCutCallbackI 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 generation of disjunctive 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 there.

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