computeSelfCost
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 classTableModify
- Parameters:
planner
- Planner for cost calculationmq
- Metadata query- Returns:
- Cost of this plan (not including children)
-
copy
Description copied from interface:RelNode
Creates a copy of this relational expression, perhaps changing traits and inputs.Sub-classes with other important attributes are encouraged to create variants of this method with more parameters.
- Specified by:
copy
in interfaceRelNode
- Overrides:
copy
in classAbstractRelNode
- Parameters:
traitSet
- Trait setinputs
- Inputs- Returns:
- Copy of this relational expression, substituting traits and inputs
