getNextElement in class LookAheadIteration<E extends ExtensibleStatement>

Returns:

The next element, or null if no more elements are available.

handleClose

protected void handleClose()

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.

Specified by:
