tools.Quadra<F,S,T,Fo>

public class Quadra<F,S,T,Fo> extends Object implements Serializable

儲存四個異質型別值的不可變泛型容器，為 Pair 與 Triple 的四元組擴充。

以型別參數 F、S、T、Fo 分別持有 first、second、third、forth 四個公開欄位，實作 Serializable 以支援序列化。提供對應的 getter 方法與完整的 equals/hashCode/toString 實作。

在 TWMS v149 中作為輕量值持有物件，用於需要同時傳遞四個不同型別資料而不值得獨立建立類別的場合。
