IloCplex::CutCallbackI
from a user-written callback. More than one cut can be added in this callback by calling
the method add or addLocal multiple times. All added cuts must be linear.
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

protected CutCallbackI()
This constructor creates a callback for use in an application with a user-defined cut to
solve a MIP.
protected IloConstraint add(IloConstraint con)
This method adds a cut for the constraint indicated by con. This cut must be globally
valid; it will not be removed by backtracking or any other means during the search. The
added cut must be linear.
protected IloConstraint addLocal(IloConstraint con)
This method adds a local cut for the constraint indicated by con. IloCplex will
manage the local cut in such a way that it will be active only when processing nodes of
this subtree. The added cut must be linear.
