Class IlcGoal

Goals are the building blocks of search algorithms in Solver. Goals depend on two classes: IlcGoal and IlcGoalI. The class IlcGoal is the handle class. An instance of the class IlcGoal contains a data member (the handle pointer) that points to an instance of the class IlcGoalI (the implementation object) allocated on the Solver heap. If you define a new class of goals, you must define the implementation class together with the corresponding virtual member function, execute, and a member function that returns an instance of the handle class IlcGoal.

For more information, see the concept Goal.

This constructor creates a goal which is empty, that is, one whose handle pointer is null. This object must then be assigned before it can be used, exactly as when you declare a pointer.

This constructor creates a handle object (an instance of the class IlcGoal) from a pointer to an implementation object (an instance of the implementation class IlcGoalI).

This member function returns a pointer to the implementation object of the invoking handle, a goal.

This member function returns the solver (a handle, an instance of IloSolver) associated with the invoking goal.

This assignment operator copies goal into the invoking goal by assigning an address to the handle pointer of the invoking object. That address is the location of the implementation object of the argument goal.

This copy constructor creates a reference to a goal. That goal and goal both point to the same implementation object.

This member function returns an instance of IloSolver associated with the invoking object.

This member function returns a pointer to the implementation object of the solver where the invoking object was extracted.
