Java Type Generic as Argument for GSON

Question

In GSON to get a list of objects you do

Gson gson = new Gson();
Type token = new TypeToken>(){}.getType();
return gson.fromJson(json         


        

Answer 1

In Kotlin you can simply use this function:

inline fun  fromJson(json: String): T {
  return Gson().fromJson(json, object: TypeToken(){}.type)
}

and use it like

val myTypes: List = fromJson(jsonString);

It will parse any object including gereric types as List. Keyword inline and reified ensures that type will not be erased.
