Description

Constructors
Methods
An instance of the class IloCplex::FractionalCutCallbackI 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 fractional 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.

protected FractionalCutCallbackI()
This constructor creates a callback for use in an application where fractional cuts are
generated.
protected IloNum getProgress()
This method returns the fraction of completion of the fractional cut generation pass.
