Date: 2012/06/28 OO training – homework 3 review
- 2 - Context與工廠職責分離 • new class的動作與使用class的動作分開 – context為使用場景 –
生成物件為工廠的職責 – 使用class都應相依於介面
- 3 - 職責分離 • BL也要遵守單一職責原則 – 商業邏輯不代表得把domain併在一起 • 禁止跨層叫用
– 例如:頁面叫用DA層
- 4 - 依賴於介面 • 物件相依於介面,而非實體 class • Log, Setting,
DA 的介面使用 – 開放封閉原則 – 容易抽換 • 物件結合方式 – constructor – public property – 注意!沒有值給預設值作法的問題 • 應改為 assert / contract 方式的防呆與檢查 • 或透過 overload 無參數 constructor 來給預設值
- 5 - 封裝 • 介面上只開放需要用的方法 – YAGNI ( You
ain’t gonna need it ! ) 原則 • 將實作細節封裝成抽象意義 – 將QueryString封裝成property – 將ViewState封裝成property
