An instance of the class IloCplex::FlowMIRCutCallbackI 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 member function to check on the progress of the generation of Flow MIR 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.

Method Detail

FlowMIRCutCallbackI

protected FlowMIRCutCallbackI(IloEnv env)
This constructor creates a callback for use in an application where flow MIR cuts are generated.

getProgress

public IloNum getProgress() const
This method returns the fraction of completion of the cut generation pass for FlowMIR cuts.

getType

protected Callback::Type getType() const

This method returns the callback type of the invoking callback object.
