I have a org.json.JSONArray that contains JSONObjects and I am trying to map those to a POJO. I know the type of the POJO I want to map to. I have 2 options and I m trying to figure out which is better in performance.
Option 1:
ObjectMapper mapper = new ObjectMapper();
ObjectReader reader = mapper.reader().withType(MyPojo.class);
for (int i = 0; i < jsonArr.length(); i++) {
JSONObject obj = jsonArr.getJSONObject(i);
MyPojo pojo = reader.readValue(obj.toString());
... other code dealing with pojo...
}
Option 2:
ObjectReader mapper = new ObjectMapper();
for (int i = 0; i < jsonArr.length(); i++) {
JSONObject obj = jsonArr.getJSONObject(i);
MyPojo pojo = mapper.convertvalue(obj, MyPojo.class);
... other code dealing with pojo...
}
For sake of argument, lets assume the length of the JSONArray is 100.
From what I have looked so far from the source code, option 1 seems better since the Deserialization context and the Deserializer is created only once, while in case of option 2, it will be done for each call.
Thoughts?
Thanks!
