An instance of the class INumToNumSegmentFunctionCursor allows you to inspect the contents of an . 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.

Note
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.
