@Immutable
public final class JsonResponse
extends Object

JSON response.

This response decorator is able to parse HTTP response body as a JSON document and manipulate with it afterwords, for example:

 String name = new JdkRequest("http://my.example.com")
   .header(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON)
   .fetch()
   .as(JsonResponse.class)
   .json()
   .readObject()
   .getString("name");

The class is immutable and thread-safe.
