Class SameTermFilterOptimizer.StopAtScopeChange

java.lang.Object

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

org.eclipse.rdf4j.query.algebra.evaluation.optimizer.SameTermFilterOptimizer.StopAtScopeChange

All Implemented Interfaces:

QueryModelVisitor<RuntimeException>

Direct Known Subclasses:

SameTermFilterOptimizer.VarBinder, SameTermFilterOptimizer.VarRenamer

Enclosing class:

SameTermFilterOptimizer

private static class SameTermFilterOptimizer.StopAtScopeChange
extends AbstractSimpleQueryModelVisitor<RuntimeException>

If that variable is not in the same scope the optimization will be invalid. So we must stop here.
