Retrofit 2.x custom type adapter

Question

I am using retrofit 2.x.I have to parse a json response whose structure is as follows:

• ->query(object)
  • -->results(object)
    • --->Scorecard(can be list or object)
      • ---->past_ings(can be list or object)
      • ---->result(can be primitive or object)

here is the link for the json test response that contains all the scenarios listed above-json

Please suggest a way to do so:)
