                   throws QueryEvaluationException

Throws:

Method Details

hasNext

public boolean hasNext()
                throws QueryEvaluationException

Description copied from interface: Iteration

Returns true if the iteration has more elements. (In other words, returns true if Iteration.next() would return an element rather than throwing a NoSuchElementException.)

Returns:

true if the iteration has more elements.

Throws:

QueryEvaluationException

next

public List<Value> next()
                 throws QueryEvaluationException

Description copied from interface: Iteration

Returns the next element in the iteration.

Returns:

the next element in the iteration.

Throws:

QueryEvaluationException

remove

public void remove()
            throws QueryEvaluationException

Description copied from interface: Iteration

Removes from the underlying collection the last element returned by the iteration (optional operation). This method can be called only once per call to next.

Throws:

QueryEvaluationException

handleClose

public void handleClose()
                 throws QueryEvaluationException

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 AbstractCloseableIteration<List<Value>, QueryEvaluationException>

Throws:

QueryEvaluationException
