org.eclipse.rdf4j.query.algebra.helpers.AbstractQueryModelVisitor<RuntimeException>

org.eclipse.rdf4j.query.algebra.evaluation.impl.QueryModelNormalizer

All Implemented Interfaces:

QueryOptimizer, QueryModelVisitor<RuntimeException>

@Deprecated(forRemoval=true,
            since="4.1.0")
public class QueryModelNormalizer
extends AbstractQueryModelVisitor<RuntimeException>
implements QueryOptimizer

Deprecated, for removal: This API element is subject to removal in a future version.

since 4.1.0. Use QueryModelNormalizerOptimizer instead.

A query optimizer that (partially) normalizes query models to a canonical form. Note: this implementation does not yet cover all query node types.
