getNextElement
Description copied from class:LookAheadIterationGets the next element. Subclasses should implement this method so that it returns the next element.- Specified by:
getNextElementin classLookAheadIteration<BindingSet,QueryEvaluationException> - Returns:
- The next element, or null if no more elements are available.
- Throws:
QueryEvaluationException
-
computeResult
- Throws:
QueryEvaluationException
-
handleClose
Description copied from class:AbstractCloseableIterationCalled byAbstractCloseableIteration.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:
handleClosein classLookAheadIteration<BindingSet,QueryEvaluationException> - Throws:
QueryEvaluationException
