Creating a Trace Object

INDEX

PREVIOUS NEXT

To get all the information about the modifications of traced activities, we create an instance of the class IlcSchedulerPrintTrace at the beginning of the search. We build a goal like this:

ILCGOAL1(SetTraceIlc, IlcInt, traceLevel) {
  IloSolver solver = getSolver();
  IlcScheduler scheduler(solver);
  IlcSchedulerPrintTrace trace(scheduler);
  solver.setTraceMode(IlcTrue);

We first create a trace object that is used to specify which objects must be traced, then instruct Solver to turn on its trace mode (otherwise the trace object would do nothing).
