Class IloCplex.SimplexCallback

java.lang.Object

ilog.cplex.IloCplex.Callback

ilog.cplex.IloCplex.OptimizationCallback

ilog.cplex.IloCplex.ContinuousCallback

ilog.cplex.IloCplex.SimplexCallback

All Implemented Interfaces:

java.lang.Cloneable

Enclosing class:

IloCplex

public abstract static class IloCplex.SimplexCallback
extends IloCplex.ContinuousCallback

This is the callback class to use when IloCplex uses the simplex optimizer.

An instance of this class represents a user-written callback in an application that uses an instance of IloCplex to solve a problem by means of the (primal or dual) simplex optimizer. For more information on the simplex optimizers, see the CPLEX User's Manual.

IloCplex calls the user-written callback at the end of each simplex iteration.

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.SimplexCallback

protected IloCplex.SimplexCallback()

Constructor for a user-written simplex callback. This constructor can be called only to construct objects of derived user-written callback classes, but not to construct IloCplex.SimplexCallback objects directly.
