react-native 友盟统计 onEventWithMap onEventObject 这两事件有什么区别？

Question

比如我现在先传递一个 object，到底是用 onEventWithMap 还是用 onEventObject 呢？

官方的demo, 请问这两个方法区别是什么呢？

    @ReactMethod
    public void onEventWithMap(String eventId, ReadableMap map) {
        Map<String, String> rMap = new HashMap<String, String>();
        ReadableMapKeySetIterator iterator = map.keySetIterator();
        while (iterator.hasNextKey()) {
            String key = iterator.nextKey();
            if (ReadableType.Array == map.getType(key)) {
                rMap.put(key, map.getArray(key).toString());
            } else if (ReadableType.Boolean == map.getType(key)) {
                rMap.put(key, String.valueOf(map.getBoolean(key)));
            } else if (ReadableType.Number == map.getType(key)) {
                rMap.put(key, String.valueOf(map.getInt(key)));
            } else if (ReadableType.String == map.getType(key)) {
                rMap.put(key, map.getString(key));
            } else if (ReadableType.Map == map.getType(key)) {
                rMap.put(key, map.getMap(key).toString());
            }
        }
        MobclickAgent.onEvent(context, eventId, rMap);
    }

@ReactMethod
    public void onEventObject(String eventID, ReadableMap property) {
        Map<String, Object> map = new HashMap();
        ReadableMapKeySetIterator iterator = property.keySetIterator();
        while (iterator.hasNextKey()) {
            String key = iterator.nextKey();
            if (ReadableType.Array == property.getType(key)) {
                map.put(key, property.getArray(key).toString());
            } else if (ReadableType.Boolean == property.getType(key)) {
                map.put(key, String.valueOf(property.getBoolean(key)));
            } else if (ReadableType.Number == property.getType(key)) {
                map.put(key, String.valueOf(property.getInt(key)));
            } else if (ReadableType.String == property.getType(key)) {
                map.put(key, property.getString(key));
            } else if (ReadableType.Map == property.getType(key)) {
                map.put(key, property.getMap(key).toString());
            }
        }

        MobclickAgent.onEventObject(context, eventID, map);

    }
