Abstract Value Members

  1. abstract def apply[T](on: ExpressionDag[N]): (N[T]) ⇒ Option[N[T]]

    If the given Id can be replaced with a simpler expression, return Some(expr) else None.

    If the given Id can be replaced with a simpler expression, return Some(expr) else None.

    If it is convenient, you might write a partial function and then call .lift to get the correct Function type
