Kotlin: How to access nested object or property by var?
0
Is there a native way in kotlin to access a nested complex object (parsed from JSON string) through a variable?
Smth similar to:
var = "Obj4"
a = Obj1.Obj2.Obj3.$var.Obj5.Array[index]
Thanks a lot in advance

I think you're looking for reflextion. kotlinlang.org/docs/reference/reflection.html It's not dymanimacally-typed language where everything is map, so you'll need to find field with reflection.

Yep, I c. That would be like val name = p.javaClass.kotlin.memberProperties.first it.name == "name" .get(p)

Using the reflection. Don't forget to add the dependency.
Global inline extension fun for Any:
inline fun <reified T : Any> Any.getThroughReflection(propertyName: String): T?
val getterName = "get" + propertyName.capitalize()
return try
javaClass.getMethod(getterName).invoke(this) as? T
catch (e: NoSuchMethodException)
null
