Interface JsonObject

All Superinterfaces:
JsonStructure, JsonValue, Map<String,JsonValue>
public interface JsonObject extends JsonStructure, Map<String,JsonValue>
A JsonObject, e.g. 
 {
     "name":"karl",
     "age":38,
     "address": {
         "street":"dummystreet"
         "housenumber":12
     }
 }
A JsonObject is always also a Map which uses the attribute names as key mapping to their JsonValues.
