Interface IQTreeVisitingTransformer

All Superinterfaces:

IQTreeTransformer

All Known Implementing Classes:

ChildTransformer, DefaultIdentityIQTreeVisitingTransformer, DefaultNonRecursiveIQTreeTransformer, DefaultRecursiveIQTreeVisitingTransformer, HomogeneousIQTreeVisitingTransformer, LazyRecursiveIQTreeVisitingTransformer, NoNullValuesEnforcerImpl.NotNullTopVariablePropagator, NotRequiredVariableRemoverImpl.VariableRemoverTransformer, RightProvenanceNormalizer.FreshVariableTransformer

public interface IQTreeVisitingTransformer
extends IQTreeTransformer

For composite IQ trees, the tree itself is passed as a first argument, in case the transformer does not transform the tree, so as to avoid creating unnecessary new objects.
