public final class RemoveEmptyDeleteRuleSet
extends Object

If the predicate for a delete is optimized to false, the target table scan of the delete will be replaced with an empty values node. This type of plan cannot be executed and is meaningless anyway, so we replace the entire thing with a values node.
