Class ComboRuleTest.IntermediateNode

  • All Implemented Interfaces:
    java.lang.Cloneable, org.apache.calcite.plan.RelOptNode, org.apache.calcite.rel.RelNode
    Enclosing class:
    ComboRuleTest

    private static class ComboRuleTest.IntermediateNode
    extends PlannerTests.TestSingleRel
    Intermediate node, the cost decreases as it is pushed up the tree (more inputs it has, cheaper it gets).
