  - resetTo
```
void resetTo(SegmentIteratorImpl src)
```
  - nextCurve
```
public Segment nextCurve()
```
    Moves the iterator to the next curve segment and returns the segment. The Segment is returned by value and is owned by the iterator. Note: The method can return null if there are no curves in the part.
  - nextSegment
```
public Segment nextSegment()
```
    Moves the iterator to next segment and returns the segment. The Segment is returned by value and is owned by the iterator.
  - previousSegment
```
public Segment previousSegment()
```
    Moves the iterator to previous segment and returns the segment. The Segment is returned by value and is owned by the iterator.
  - resetToFirstSegment
```
public void resetToFirstSegment()
```
    Resets the iterator so that the call to NextSegment will return the first segment of the current path.
  - resetToLastSegment
```
public void resetToLastSegment()
```
    Resets the iterator so that the call to PreviousSegment will return the last segment of the current path.

    Resets the iterator such that the subsequent call to the NextPath will set the iterator to the first segment of the first path.
  - resetToLastPath
```
public void resetToLastPath()
```
    Resets the iterator such that the subsequent call to the PreviousPath will set the iterator to the last segment of the last path.
  - resetToPath
```
public void resetToPath(int pathIndex)
```
    Resets the iterator such that the subsequent call to the NextPath will set the iterator to the first segment of the given path. The call to PreviousPath will reset the iterator to the last segment of path pathIndex - 1.
  - _getSegmentCount
```
public int _getSegmentCount(int pathIndex)
```
  - isClosingSegment
```
public boolean isClosingSegment()
```
    Returns True, if the segment is the closing segment of the closed path
