- net.sf.saxon.expr.elab.IndexedVariableEvaluator

All Implemented Interfaces:

SequenceEvaluator
```
public class IndexedVariableEvaluator
extends java.lang.Object
implements SequenceEvaluator
```
Evaluator for a variable that needs to be indexed, because the optimizer has identified that it will contain a sequence that is accessed using predicates based on the content Note, indexing is only used in Saxon-EE; the implementation in Saxon-HE is a dummy.
