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.
以下哪个是其中一个理由来包装遗留(传统)的代码？
1 避免了重写遗留代码的现代化接口和访问这些代码，可以节省开发时间。
2 遗留代码，接口所需的参数匹配提供新的应用程序。
3 为了提高性能，新系统需要直接访问遗留系统维护的数据。
4 遗留代码写在一个旧的，但在您的新系统（C / C++等）兼容的版本使用的语言。
5 在未来版本的应用程序内部的遗留代码需要重写。
