IloNumToNumSegmentFunctionCursor

```
public interface IloNumToNumSegmentFunctionCursor
```
An instance of the class IloNumToNumSegmentFunctionCursor allows you to inspect the contents of an IloNumToNumSegmentFunction. A segment of a piecewise linear function is defined as an interval [x1, x2) over which the function is linear. Cursors are intended to iterate forward or backward over the segments of a piecewise linear function.
The structure of the piecewise linear function cannot be changed while a cursor is being used to inspect it. Therefore, functions that change the structure of the piecewise linear function, such as , should not be called while the cursor is being used.

Method Summary

Methods
Modifier and Type	Method and Description
`double`	`getSegmentMax()` This member function returns the right-most point of the segment currently specified by the cursor.
`double`	`getSegmentMin()` This member function returns the left-most point of the segment currently specified by the cursor.
`double`	`getValue(double t)` This member function returns the value of the piecewise linear function at time `t`.
`double`	`getValueLeft()` This member function returns the value of the function at the left-most point of the segment currently specified by the cursor.
`double`	`getValueRight()` This member function returns the value of the function at the right-most point of the segment currently specified by the cursor.
`void`	`next()` This operator moves the cursor to the segment adjacent to the current step (forward move).
`boolean`	`ok()` This member function returns `IloFalse` if the cursor does not currently specify a segment included in the definition interval of the piecewise linear function.
`void`	`previous()` This operator moves the cursor to the segment adjacent to the current step (backward move).
`void`	`seek(double f)` This member function sets the cursor to specify the segment of the function that contains the argument.

- Method Detail
  - ok
```
boolean ok()
```
    This member function returns IloFalse if the cursor does not currently specify a segment included in the definition interval of the piecewise linear function. Otherwise, it returns IloTrue.
  - next
```
void next()
```
    This operator moves the cursor to the segment adjacent to the current step (forward move).
  - previous
```
void previous()
```
    This operator moves the cursor to the segment adjacent to the current step (backward move).
  - seek
```
void seek(double f)
```
    This member function sets the cursor to specify the segment of the function that contains the argument. An IloException is thrown if the argument does not belong to the definition interval of the piecewise linear function associated with the invoking cursor.
  - getSegmentMin
```
double getSegmentMin()
```
    This member function returns the left-most point of the segment currently specified by the cursor.
  - getSegmentMax
```
double getSegmentMax()
```
    This member function returns the right-most point of the segment currently specified by the cursor.
  - getValueLeft
```
double getValueLeft()
```
    This member function returns the value of the function at the left-most point of the segment currently specified by the cursor.
  - getValueRight
```
double getValueRight()
```
    This member function returns the value of the function at the right-most point of the segment currently specified by the cursor.
  - getValue
```
double getValue(double t)
```
    This member function returns the value of the piecewise linear function at time t. t must be between the left-most and the right-most point of the segment currently specified by the cursor.
