    • javason

      public static Map<String,Object> javason(String javason)

This means you can express a snippit of JSON without having to forward slash escape everything. This is character based, so don't have any apostrophes (') in your test data.
      Parameters:
      javason - JSON-ish string you want to turn into Maps-of-Maps
      Returns:
      Maps-of-Maps
