    • Method Detail

      • copy

        public RelNode copy​(RelTraitSet traitSet,
                            java.util.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
      • register

        public void register​(RelOptPlanner planner)
        Description copied from interface: RelNode
        Registers any special rules specific to this kind of relational expression.

        The planner calls this method this first time that it sees a relational expression of this class. The derived class should call RelOptPlanner.addRule(org.apache.calcite.plan.RelOptRule) for each rule, and then call super.register.

        Specified by:
        register in interface RelNode
        register in class AbstractRelNode
        planner - Planner to be used to register additional relational expressions
