Enclosing class:

IloCplex

public abstract static class IloCplex.ProbingCallback
extends IloCplex.MIPCallback

Base class for user-written control and query callbacks that control probing progress.

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.ProbingCallback

protected IloCplex.ProbingCallback()

Constructor for user-written probing callbacks.

This constructor can be called only to construct objects of derived user-written callback classes, but not to construct ProbingCallback objects directly.

Method Detail

getPhase

protected int getPhase()
                throws IloException

Returns the current phase of probing.

Throws:

IloException

Returns:

The current probing phase.

getProgress

protected double getProgress()
                      throws IloException

Returns the fraction of completion of the current probing phase.

This value is between 0.0 and 1.0.

Throws:

IloException

Returns:

The fraction of the completion of the current probing phase.
