TransformReorder (Apache Jena ARQ)

java.lang.Object
- org.apache.jena.sparql.algebra.TransformCopy
- - org.apache.jena.sparql.algebra.optimize.TransformReorder

All Implemented Interfaces:

Transform
```
public class TransformReorder
extends TransformCopy
```
A Transformer that applies a reordering to all BGPs and Quad Patterns present in the algebra
This transformer may be slightly naive in that it only leverages the ReorderTransformation.reorder(BasicPattern) method and does not use the ReorderTransformation.reorderIndexes(BasicPattern) method at all so may not achieve the best reordering
