[contrib #388] apply implcit def to return types (relax overriding rules) |
| code |
import scala.xml.{NodeSeq, Elem}
class EO extends Application with Moo{
def cat = <cat>dog</cat>
implicit def nodeSeqToFlog(in: Elem): Flog = new Flog(in)
}
trait Moo {
def cat: Flog
}
class Flog(val in: NodeSeq) |
| what happened |
Compiler error that Elem is not a Flog
|
| what expected |
Apply nodeSeqToFlog to convert the Elem to a Flog without having to explicitly say def cat: Flog = <cat>dog</cat>
The OP actually wants to have more relaxed rules for overriding, so that a method with an unrelated return type can still override, and let the compiler apply an implicit def to convert between the actual return type and the inherited one. |
