| <div class="block">Transformer that walks over a tree of relational expressions, replacing each |
| <a href="../rel/RelNode.html" title="interface in org.apache.calcite.rel"><code>RelNode</code></a> with a 'slimmed down' relational expression that projects |
| only the columns required by its consumer. |
| |
| <p>Uses multi-methods to fire the right rule for each type of relational |
| expression. This allows the transformer to be extended without having to |
| add a new method to RelNode, and without requiring a collection of rule |
| classes scattered to the four winds. |
| |
| <p>REVIEW: jhyde, 2009/7/28: Is sql2rel the correct package for this class? |
| Trimming fields is not an essential part of SQL-to-Rel translation, and |
| arguably belongs in the optimization phase. But this transformer does not |
| obey the usual pattern for planner rules; it is difficult to do so, because |
| each <a href="../rel/RelNode.html" title="interface in org.apache.calcite.rel"><code>RelNode</code></a> needs to return a different set of fields after |
| trimming. |
| |
| <p>TODO: Change 2nd arg of the <a href="#trimFields(org.apache.calcite.rel.RelNode,org.apache.calcite.util.ImmutableBitSet,java.util.Set)"><code>trimFields(org.apache.calcite.rel.RelNode, org.apache.calcite.util.ImmutableBitSet, java.util.Set<org.apache.calcite.rel.type.RelDataTypeField>)</code></a> method from BitSet to |
| Mapping. Sometimes it helps the consumer if you return the columns in a |
| particular order. For instance, it may avoid a project at the top of the |
| tree just for reordering. Could ease the transition by writing methods that |
| convert BitSet to Mapping and vice versa.</div> |
