Returns a copy of this node where rule has been recursively applied to the tree. When rule does not apply to a given node, it is left unchanged.

references are the same;
the order is equal too.

Definition Classes: LogicalPlan

final def sameResult(other: LogicalPlan): Boolean

Returns true when the given query plan will return the same results as this query plan.

Since its likely undecidable to generally determine if two given plans will produce the same results, it is okay for this function to return false, even if the results are actually the same. Such behavior will not affect correctness, only the application of performance enhancements like caching. However, it is not acceptable to return true if the results could possibly be different.

This function performs a modified version of equality that is tolerant of cosmetic differences like attribute naming and or expression id differences.
