public static com.squareup.moshi.JsonReader enterPath​(com.squareup.moshi.JsonReader reader,
                                                      java.lang.String path1,

                                               throws java.io.IOException
        This saves you from having to define nested types to read a single value

        Instead of defining two types like this, and double-checking null.. 

        
 class Response {
   Message message;
 }
 class Message {
   String status;
 }
 JsonAdapter<Response> adapter = moshi.adapter(Response.class);
 Message message = adapter.fromJson(body.source());
 if (message != null && message.status != null) throw new IllegalStateException(message.status);

        You can advance to the field directly. 

        
 JsonReader status = enterPath(JsonReader.of(body.source()), "message", "status");
 if (status != null) throw new IllegalStateException(status.nextString());
        Throws:
        java.io.IOException
