computeSelfCost
public RelOptCost computeSelfCost(RelOptPlanner planner, RelMetadataQuery mq)
Description copied from interface:RelNode
Returns the cost of this plan (not including children). The base implementation throws an error; derived classes should override.NOTE jvs 29-Mar-2006: Don't call this method directly. Instead, use
RelMetadataQuery.getNonCumulativeCost(org.apache.calcite.rel.RelNode)
, which gives plugins a chance to override the rel's default ideas about cost.- Specified by:
computeSelfCost
in interfaceRelNode
- Overrides:
computeSelfCost
in classFilter
- Parameters:
planner
- Planner for cost calculationmq
- Metadata query- Returns:
- Cost of this plan (not including children)
-
