-// An ObjectWriter implementation that outputs JSON. This ObjectWriter
-// supports writing a compact form or a pretty printed form.
-//
-// Sample usage:
-//   string output;
-//   StringOutputStream* str_stream = new StringOutputStream(&output);
-//   CodedOutputStream* out_stream = new CodedOutputStream(str_stream);
-//   JsonObjectWriter* ow = new JsonObjectWriter("  ", out_stream);
-//   ow->StartObject("")
-//       ->RenderString("name", "value")
-//       ->RenderString("emptystring", string())
-//       ->StartObject("nested")
-//         ->RenderInt64("light", 299792458);
-//         ->RenderDouble("pi", 3.141592653589793);
-//       ->EndObject()
-//       ->StartList("empty")
-//       ->EndList()
-//     ->EndObject();
-//
-// And then the output string would become:
-// {
-//   "name": "value",
-//   "emptystring": "",
-//   "nested": {
-//     "light": "299792458",
-//     "pi": 3.141592653589793
-//   },
-//   "empty": []
-// }
-//
-// JsonObjectWriter does not validate if calls actually result in valid JSON.
-// For example, passing an empty name when one would be required won't result
-// in an error, just an invalid output.
-//
-// Note that all int64 and uint64 are rendered as strings instead of numbers.
-// This is because JavaScript parses numbers as 64-bit float thus int64 and
-// uint64 would lose precision if rendered as numbers.
-//
-// JsonObjectWriter is thread-unsafe.
