单身模式 - 设计问题 [英] singleton pattern - design question

问题描述

您好，

我正在构建一个应用程序，我有一个ConfigManager类来保存有关应用程序的所有重要信息。

我只需要一个ConfigManager类的实例，可以在整个应用程序中从应用程序内的任何位置使用。根据我的阅读，单例模式似乎与我的问题相符

但是，我使用带参数的构造函数构建了ConfigManager。


到现在为止，我'尝试过使用全局变量。 ConfigManager类的一个实例声明为全局并在整个应用程序中使用。它有效，但我对此并不十分舒服。这就是我需要第二意见的原因。

谢谢，

Hello,
I''m building an application, in which I have a ConfigManager class to hold all the important info about the application.
I need only one instance of ConfigManager class to be available throughout the application, from anywhere inside the application. From what I have read, the singleton pattern seems to match my problem
However, I built the ConfigManager with a constructor with parameters.

Until now, I''ve tried using global variables. One instance of ConfigManager class declared as global and used throughout th app. It works, but I am not very confortable with this. That''s why I need a second opinion.

Thanks,

Adina

您是否尝试创建单例，然后（创建和）使用setVariable（）方法？

Have you tried to create the singleton, and then (creating and) using setVariable() methods?

据我所知，你可以使用参数化构造函数创建单例，但问题是谁将分配参数？如果你能做出那个决定那么就有可能。尝试查看 http://ehsanbraindump.blogspot.com ，它有一些关于单身人士的好内容。

As far as I know you can create singleton''s with parameterized constructors but the problem is who will assign the parameters? If you can make that decision then it will be possible. Try lookin in http://ehsanbraindump.blogspot.com it has some good content on singletons.
