Class IloSolution::Iterator

Iterator is a class nested in the class IloSolution. It allows you to traverse the variables in a solution. The iterator scans the objects in the same order as they were added to the solution.

This iterator is not robust. If the variable at the current position is deleted from the solution being iterated over, the behavior of this iterator afterward is undefined.

• iter can be safely used after the following code has executed:

 IloExtractable elem = *iter;

 ++iter;

 solution.remove(elem);
 

• iter cannot be safely used after the following code has executed:

 solution.remove(*iter); // bad idea

 ++iter;
 

This constructor creates an iterator to traverse the variables of solution. The iterator traverses variables in the same order they were added to solution.

This member function returns IloTrue if the current position of the iterator is a valid one. It returns IloFalse if all variables have been scanned by the iterator.

This operator returns the extractable object corresponding to the variable located at the current iterator position. If all variables have been scanned, this operator returns an empty handle.

This operator moves the iterator to the next variable in the solution.
