createIteration
protected Iteration<BindingSet,QueryEvaluationException> createIteration() throws QueryEvaluationException
Deprecated.Description copied from class:DelayedIterationCreates the iteration that should be iterated over. This method is called only once, when the iteration is first needed.- Specified by:

QueryEvaluationException
-
decrement
protected void decrement(int amount) throws QueryEvaluationExceptionDeprecated.- Throws:
QueryEvaluationException
-
remove
public void remove() throws QueryEvaluationExceptionDeprecated.Description copied from class:DelayedIterationCalls the remove method of the underlying iteration.- Specified by:
removein interfaceIteration<BindingSet,QueryEvaluationException>- Overrides:
