@Deprecated(since="4.1.0") public class SPARQLMinusIteration extends FilterIteration<BindingSet>
Deprecated.
An Iteration that returns the results of an Iteration (the left argument) MINUS any results that are compatible with results of another Iteration (the right argument) or that have no shared variables. This iteration uses the formal definition of the SPARQL 1.1 MINUS operator to determine which BindingSets to return.
