Note: This question is not a duplicate of How can I get all object vals and subobject vals using reflection in Scala?
The answer provided in that question only works for final members.
For example:
scala> object Settings {
| val Host = "host"
| }
defined module Settings
deepMembers(Settings)
res0: Map[String,String] = Map()
It must be a duplicate, but I need a refresher:
$ scala
Welcome to Scala version 2.11.7 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_45).
Type in expressions to have them evaluated.
Type :help for more information.
scala> object Settings { val Host = "host" ; val Guest = "guest" }
defined object Settings
scala> import reflect.runtime._,universe._
import reflect.runtime._
import universe._
scala> val im = currentMirror reflect Settings
im: reflect.runtime.universe.InstanceMirror = instance mirror for Settings$@c8e4bb0
scala> im.symbol.asClass.typeSignature.members filter (s => s.isTerm && s.asTerm.isAccessor)
res0: Iterable[reflect.runtime.universe.Symbol] = SynchronizedOps(value Guest, value Host)
scala> res0 map (im reflectMethod _.asMethod) map (_.apply())
res2: Iterable[Any] = List(guest, host)
val members = Settings.getClass.getDeclaredFields.map(_.getName).filterNot(_ == "MODULE$")
members: Array[String] = Array(Host)
This works but I think there's certainly a better way of doing this.
