Method Detail

transformTo

public void transformTo(RelNode rel)

Description copied from class: RelOptRuleCall

Called by the rule whenever it finds a match. The implementation of this method will guarantee that the original relational expression (e.g., this.rels[0]) has its traits propagated to the new relational expression (rel) and its unregistered children. Any trait not specifically set in the RelTraitSet returned by rel.getTraits() will be copied from this.rels[0].getTraitSet().
