| This is a conservative and relatively limited optimization and has been |
| superseded in the default optimizer by the <a href="TransformFilterPlacement.html" title="class in org.apache.jena.sparql.algebra.optimize"><code>TransformFilterPlacement</code></a> |
| as of the 2.11.x releases. This original version of TransformFilterPlacement |
| only operates on filters over BGPs, quad blocks, sequences and conditions |
| (a form of LeftJoin with no scope issues) of the same. |
| However in some cases it may be desirable to have |
| the more limited and conservative behaviour so this is preserved in the code |
| for those who want to use this. |
| </p> |

| The context flag <a href="../../../query/ARQ.html#optFilterPlacementConservative"><code>ARQ.optFilterPlacementConservative</code></a> may be set to |
| have the default optimizer use this in place of the newer and more aggressive |
