Example 1 with QueryAggregation

the class AggregationDeserializer method deserialize.

 *
 * @param json the JSON data being deserialized
 * @param typeOfT the type to deserialize to, which should be {@link QueryAggregation}
 * @param context additional information about the deserialization state
 * @return the appropriate {@link QueryAggregation} subclass
 * @throws JsonParseException signals that there has been an issue parsing the JSON
