An instance of the class INumToNumStepFunctionCursor allows you to inspect the contents of an instance of IloNumToNumStepFunction. A step of a step function is defined as an interval [x1,x2) over which the value of the function is the same. Cursors are intended to iterate forward or backward over the steps of a step function.

Note
The structure of the step function cannot be changed while a cursor is being used to inspect it. Therefore, methods that change the structure of the step function, such as IloNumToNumStepFunction::setValue, should not be called while the cursor is being used.
