How to use scala reflection API to get all contained classes

Question

I got this kind of class:

trait ThirdParty { def invoke = println(\"right\") }

trait WeatherIcon { def invoke = println(\"wrong\") }

class MyClass {

    o         


        

Answer 1

I can't offer a complete solution, but maybe this is a start:

import reflect.runtime.universe._

val myClassType = typeOf[MyClass]    // Get the type of McClass
val thirdPartyType = typeOf[ThirdParty] // Get the type of ThirdParty
val methodToInvoke = newTermName("invoke")

val declsOfMyClass = myClassType.declarations // Get the declarations of MyClass

val subtypesOfThirdParty = 
  declsOfMyClass.filter(_.typeSignature.parents.contains(thirdPartyType))

val methodsToInvoke =             // Now we have the methods.
  subtypesOfThirdParty.map(tps => tps.typeSignature.member(methodToInvoke))

// TODO: Invoke!

I guess there is a much more straight-forward way than this.
