Kotlinでデータクラスの空のコンストラクタを作成する方法

データクラスに10以上のパラメーターがあり、空のコンストラクタでデータクラスを初期化して、値をセットする方法が調べても出てこなかったので、メモを残しておく。

データクラスの生成方法 :

data class XxxData(
        var updated_on: String,
        var tags: List<String>,
        var description: String,
        var user_id: List<Int>,
        var status_id: Int,
        var title: String,
        var created_at: String,
        var data: HashMap<*, *>,
        var id: Int,
        var counts: LinkedTreeMap<*, *>,
)

使い方 :

val activity =  Activity();
activity.title = "New Computer"
sendToServer(activity)

こうやって、パラメータに値をセットしておくことで、空のコンストラクタを生成することができるようになる。
