which one of the following is reason to wrap legacy code?
1 Development time can be saved by avoiding the rewriting of legacy code yet modernize interfaces and access to that code.
2 The parameters required by the legacy code interfaces match those provided in the new application.
3 To improve performance, the new system needs to directly access data maintained by the legacy system.
4 The legacy code was written in an older but compatible version of language used in your new system(c/c++,for example).
5 Internal parts of the legacy code need to be rewritten in the next version of the application.
以下哪個(gè)是其中一個(gè)理由來包裝遺留(傳統(tǒng))的代碼?
1 避免了重寫遺留代碼的現(xiàn)代化接口和訪問這些代碼,可以節(jié)省開發(fā)時(shí)間。
2 遺留代碼,接口所需的參數(shù)匹配提供新的應(yīng)用程序。
3 為了提高性能,新系統(tǒng)需要直接訪問遺留系統(tǒng)維護(hù)的數(shù)據(jù)。
4 遺留代碼寫在一個(gè)舊的,但在您的新系統(tǒng)(C / C++等)兼容的版本使用的語(yǔ)言。
5 在未來版本的應(yīng)用程序內(nèi)部的遺留代碼需要重寫。
