public java.lang.Object clone()
```
    Description copied from class: IndexInput
    
    Returns a clone of this stream.
    Clones of a stream access the same data, and are positioned at the same point as the stream they were cloned from.
    Expert: Subclasses must ensure that clones may be positioned at different points in the input from each other and from the stream they were cloned from.
