Note:This is an advanced routine. Advanced routines typically demand a profound
understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher
risk of incorrect behavior in your application, behavior that can be difficult to
debug. Therefore, ILOG encourages you to consider carefully whether you can
accomplish the same task by means of other Callable Library routines instead.
An instance of the class IloCplex::LazyConstraintCallbackI represents a
user-written callback in an application that uses an instance of IloCplex to solve a
MIP while generating lazy constraints. IloCplex calls the user-written callback after
solving each node LP exactly like IloCplex::CutCallbackI. In fact, this
callback is exactly equivalent to IloCplex::CutCallbackI but offers a name
more consistently pointing out the difference between lazy constraints and user cuts.
