    • copy

      public RelNode copy(RelTraitSet traitSet, List<RelNode> inputs)
      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 interface RelNode
      copy in class AbstractRelNode
      traitSet - Trait set
      inputs - Inputs
      Copy of this relational expression, substituting traits and inputs
    • computeSelfCost

      public @Nullable 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 interface RelNode
      computeSelfCost in class ConverterImpl
      planner - Planner for cost calculation
      mq - Metadata query
      Cost of this plan (not including children)
    • implement

      Creates a plan for this expression according to a calling convention.
