hasNext
public boolean hasNext() throws QueryEvaluationExceptionDescription copied from interface:IterationReturns 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 T next() throws QueryEvaluationException
Description copied from interface:IterationReturns the next element in the iteration.- Returns:
- the next element in the iteration.
- Throws:
QueryEvaluationException
-
remove
public void remove() throws QueryEvaluationExceptionDescription copied from interface:IterationRemoves 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
protected void handleClose() throws QueryEvaluationExceptionDescription 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:
