InheritAnalysisRules

trait InheritAnalysisRules extends UnaryLike[Expression]

An add-on of RuntimeReplaceable. It makes replacement the child of the expression, to inherit the analysis rules for it, such as type coercion. The implementation should put replacement in the case class constructor, and define a normal constructor that accepts only the original parameters. For an example, see TryAdd. To make sure the explain plan and expression SQL works correctly, the implementation should also implement the parameters method.
