public class IQBasedSubstitutionPropagationExecutor<N extends QueryNode>
extends Object
implements SubstitutionPropagationExecutor<N>

TEMPORARY CODE! Substitution propagation executor for the transition from mutable Intermediate Queries to immutable IQs. Does NOT propagate UP but insert instead a ConstructionNode Propagates to the focus node and DOWN. Restriction: non ground functional terms cannot be propagated DOWN, but they can be inserted in the "ascending" construction node.
