Class IloCPTraceI

An instance of this class is used to wrap the Solver trace mechanism. It enables you to set a trace at the start of a search.

A trace wrapper is implemented by means of two classes: a handle class and an implementation class. In other words, an instance of the class IloCPTrace (a handle) contains a data member (the handle pointer) that points to an instance of the class IloCPTraceI (its implementation object).

This constructor creates a trace at the start of a search.

This destructor is called automatically by the destructor of its subclasses. It frees memory used by the objects.

Solver calls this member function when it starts the search.

If you want to use this facility, you must define this virtual member function. This member function should not be called at the same time as any other side effects of the search, such as filter levels.
