Method Details

getNextElement

protected BindingSet getNextElement()
                             throws QueryEvaluationException

Deprecated, for removal: This API element is subject to removal in a future version.

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<BindingSet>

Returns:

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

Throws:

QueryEvaluationException

computeResult

protected ArrayList<BindingSet> computeResult()
                                       throws QueryEvaluationException

Deprecated, for removal: This API element is subject to removal in a future version.

Throws:

QueryEvaluationException

handleClose

protected void handleClose()
                    throws QueryEvaluationException

Deprecated, for removal: This API element is subject to removal in a future version.

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:

handleClose in class AbstractCloseableIteration<BindingSet>

Throws:

QueryEvaluationException
