本文介紹了鉆石繼承(C++)的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學習吧！
問題描述
我知道擁有鉆石繼承被認為是不好的做法.但是，我有兩個案例，我覺得鉆石繼承非常適合.我想問一下，在這些情況下你會推薦我使用菱形繼承，還是有其他更好的設計.
I know that having diamond inheritance is considered bad practice. However, I have 2 cases in which I feel that diamond inheritance could fit very nicely. I want to ask, would you recommend me to use diamond inheritance in these cases, or is there another design that could be better.
案例 1: 我想在我的系統中創建代表不同類型操作"的類.動作由幾個參數分類:
Case 1: I want to create classes that represent different kinds of "Actions" in my system. The actions are classified by several parameters:
- 操作可以是讀取"或寫入".
- 動作可以有延遲或沒有延遲(它不僅僅是 1 個參數.它會顯著改變行為).
- 動作的流類型"可以是 FlowA 或 FlowB.
我打算有以下設計:
// abstract classes
class Action
{
// methods relevant for all actions
};
class ActionRead : public virtual Action
{
// methods related to reading
};
class ActionWrite : public virtual Action
{
// methods related to writing
};
class ActionWithDelay : public virtual Action
{
// methods related to delay definition and handling
};
class ActionNoDelay : public virtual Action {/*...*
