protected E getNextElement()

```
    Description copied from class: LookAheadIteration
    
    Gets the next element. Subclasses should implement this method so that it returns the next element.
    
    Specified by:
    
    getNextElement in class LookAheadIteration<E extends ExtensibleStatement,X extends Exception>
    
    Returns:
    
    The next element, or null if no more elements are available.
    
    Throws:
    
    X extends Exception
  - handleClose
```
protected void handleClose()
                    throws X extends Exception
```
    Description copied from class: AbstractCloseableIteration
    
    Called by AbstractCloseableIteration.close() when it is called for the first time. This method is only called once on each iteration. By default, this method does nothing.
    
    Overrides:
    
    handleClose in class LookAheadIteration<E extends ExtensibleStatement,X extends Exception>
    
    Throws:
    
    X
    
    X extends Exception
