Method Detail

hasNext
public boolean hasNext() throws QueryEvaluationException
Description copied from interface:Iteration
Returns true if the iteration has more elements. (In other words, returns true ifIteration.next()
would return an element rather than throwing a NoSuchElementException.)- Returns:
- true if the iteration has more elements.
- Throws:
QueryEvaluationException
-
next
public java.util.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 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:
