作業整理摘要
- 3 - 物件職責 • 將商品資訊聚合成為Entity • 把new Class的動作,與使用Class的動作隔開 •
物流商是否具有長、寬、高、重點等商品屬性 • 商品上是否應該擁有計算運費的方法 • 物流商的名稱,是否可由外部設定
- 4 - 重構 • 重構應確保重構後的結果,與重構前相同 – 工具 • Selenium
• 單元測試 – 例子 • 物流商配置顛倒 • double改成float或int • 衍生設計 • Visual Studio重構功能 – 擷取方法 – 擷取介面 – 封裝欄位
- 5 - DRY • 判斷式中,重複出現相同的程式碼,是否可以移出判斷式之 外 • 子類與父類相同的部份,是否只需放在父類 •
抽象來看,是否相同,不同的地方在哪
- 6 - 建議 • 每個Class獨立一個檔案 • 預設的todo註解請記得清除 – 工作清單視窗
- 7 - 衍生需求 • 當每間物流商計算運費所需要的商品資訊增加時,該如何修 改程式 • 低溫冷藏時,計算運費的方式不同 •
頁面新需求為,選擇最便宜的物流商,並呈現運費結果
- 8 - 課程補充 • new與override • overload
- 9 - Step • 把計算運費抽出來,成為BL – abstract – interface
• 把new class與使用class隔開 – function – Factory class • 把商品資訊定義成Entity • 抽象工廠 • 物流商名稱使用Enum Description
