hasNext
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.)- Specified by:
hasNext
in interfaceIteration<BindingSet,
QueryEvaluationException> - Returns:
- true if the iteration has more elements.
- Throws:
QueryEvaluationException
-
next
Description copied from interface:Iteration
Returns the next element in the iteration.- Specified by:
next
in interfaceIteration<BindingSet,
QueryEvaluationException> - Returns:
- the next element in the iteration.
- Throws:
QueryEvaluationException
-
remove
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.- Specified by:
remove
in interfaceIteration<BindingSet,
QueryEvaluationException> - Throws:
QueryEvaluationException
-
close
Description copied from interface:CloseableIteration
Closes this iteration, freeing any resources that it is holding. If the iteration has already been closed then invoking this method has no effect.- Specified by:
close
in interfaceAutoCloseable
- Specified by:
