Class Summary Class Description BadlyDesignedLeftJoinIterator BindingSetHashKey Compact and efficient representation of a binding set for use as a key in hash maps.BottomUpJoinIterator Deprecated. replaced by HashJoinIterationCollectionIteration<E,X extends Exception> Deprecated. since 2.3 useCollectionIterationCompatibleBindingSetFilter Deprecated. CrossProductIteration Iteration which forms the cross product of a list of materialized input bindings with each result obtained from the inner iteration.DelayedEvaluationIteration Utility class that removes code duplication and makes a precompiled QueryEvaluationStep available as an iteration that may be created and used later.DescribeIteration Deprecated. ExtensionIterator Deprecated. FilterIterator Deprecated. FilterIterator.RetainedVariableFilteredQueryEvaluationContext This is used to make sure that no variable is seen by the filter that are not in scope.GroupIterator HashJoinIteration Generic hash join implementation suitable for use by Sail implementations.JoinIterator Interleaved join iterator.LeftJoinIterator MultiProjectionIterator OrderIterator Deprecated. PathIteration PathIteration.ValuePair ProjectionIterator Deprecated.
