Removes the last element that has been returned from the wrapped Iteration.

Specified by:

remove in interface Iterator<E>

Overrides:

remove in class IterationWrapper<E>

handleClose

protected void handleClose()

Description copied from class: IterationWrapper

Closes this Iteration and also closes the wrapped Iteration if it is a CloseableIteration.
