界: API Abuse

API 就像是呼叫者與被呼叫者之間簽訂的規定。最常見的 API 濫用形式是由呼叫者這一當事方未能遵守此規定所造成的。例如,如果程式在呼叫 chroot() 後無法呼叫 chdir(),即違反規範如何以安全方式變更使用中根目錄的規定。程式庫濫用的另一個好例子是期待被呼叫者向呼叫者傳回值得信賴的 DNS 資訊。在這種情況下,呼叫者是透過對其行為做出某些假設 (傳回值可用於驗證目的) 來濫用被呼叫者 API。另一方也可能違反呼叫者與被呼叫者間的規定。例如,如果編碼器衍生出子類別 SecureRandom 並傳回一個非隨機值,則違反了規定。

Castor Bad Practices: Query Mode Not Read-Only

Abstract
非唯讀的 Castor 查詢會影響效能。
Explanation
即使 Castor 在物件上建立鎖定,也無法阻止其他執行緒讀取或寫入該物件。跟預設共享模式比較起來,唯讀查詢的速度大約快了七倍。

範例 1:下列範例指定查詢模式為 SHARED,允許讀取與寫入權限。

results = query.execute(Database.SHARED);
