public abstract static class IloCplex.DisjunctiveCutCallback

extends IloCplex.MIPCallback

An instance of the class DisjunctiveCutCallback 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 allows you to monitor the progress of the generation of disjunctive cuts.

This is a user-written callback class. The constructor and methods of this class are protected to make sure that they are used only to derive a user-written callback class or to implement the main method in it.

Constructor Detail

IloCplex.DisjunctiveCutCallback

protected IloCplex.DisjunctiveCutCallback()

Constructor for user-written disjunctive cut callbacks. This constructor can be called only to construct objects of derived user-written callback classes, but not to construct IloCplex.DisjunctiveCallback objects directly.

Method Detail

getProgress

protected double getProgress()
                      throws IloException

Returns the fraction of completion of the disjunctive cut generation. The returned values are in the range of 0.0 to 1.0.

Returns:

The fraction of completion of the disjunctive cut generation.
