LimitedSizeSPARQLMinusIteration
public LimitedSizeSPARQLMinusIteration(Iteration<BindingSet,QueryEvaluationException> leftArg, Iteration<BindingSet,QueryEvaluationException> rightArg, AtomicLong used, long maxSize)
Creates a new MinusIteration that returns the results of the left argument minus the results of the right argument. By default, duplicates are not filtered from the results.- Parameters:
leftArg
- An Iteration containing the main set of elements.rightArg
- An Iteration containing the set of elements that should be filtered from the main set. * @param used An atomic long used to monitor how many elements are in the set collections.used
- An atomic long used to monitor how many elements are in the set collections.maxSize
- Maximum size allowed by the sum of all collections used by the LimitedSizeQueryEvaluatlion.
