Usage

From source file:com.facebook.stetho.json.ObjectMapper.java

private JSONObject _convertToJSONObject(Object fromValue)
        throws JSONException, InvocationTargetException, IllegalAccessException {
    JSONObject jsonObject = new JSONObject();
    Field[] fields = fromValue.getClass().getFields();
    for (int i = 0; i < fields.length; ++i) {
        JsonProperty property = fields[i].getAnnotation(JsonProperty.class);
        if (property != null) {
            // AutoBox here ...
            Object value = fields[i].get(fromValue);
            Class clazz = fields[i].getType();

                clazz = value.getClass();

            String name = fields[i].getName();

                // Leave it as null in this case.
