如何处理重复的类名 [英] how to deal with duplicate class names
问题描述
我有点像c ++新手。我正在将一些静态库链接到
我的应用程序。事实证明，两个库（来自不同的
供应商）共享一个类名;例如他们都有一个名为
''SomeClass''的班级。编译器/链接器正在抱怨。是否有一个简单的
方式处理这个，所以我的应用程序可以链接？谢谢。
i''m somewhat of a c++ newbie. i''m linking some static libraries into
my app. it turns out that two of the libraries (from different
suppliers) share a class name; e.g. they both have a class named
''SomeClass''. the compiler/linker is complaining. is there an easy
way deal with this so my app can link? thanks.
推荐答案
使用命名空间，这正是它们的用途。
use namespaces, this is exactly what they are for.

创建代理类。也就是说，实现所有相同的
方法作为您遇到问题的类之一，并且
只需将所有方法调用转发给实例它代表的是
的类。如果需要，请使用PIMPL习语（请参阅Google）。

Create proxy class. That is, one that implements all of the same
methods as one of the classes with which you are having problems, and
have it simply forward all method calls to an instance of the class for
which it is proxying. If needed, use the PIMPL idiom (see Google).

不，据我所知，对不起。
但你可以在语言之外寻求解决方案。
例如，在Windows中你可以隔离其中一个类的使用
。动态链接的库。
或者，例如，你可以检查一些更高质量的库是否提供相同的功能
，你应该这样做可能
无论如何都要做 - 使用低质量的库会产生越来越多的问题，并且可能会迫使你使用不太好的设计。
一个高质量的C ++库将使用命名空间来大大减少名称冲突的
的机会，所以这是一件值得寻找的事情。

答：因为它弄乱了人们通常阅读文字的顺序。
问：为什么这么糟糕？
A：热门发布。
问：什么是m在usenet和电子邮件中发生了令人烦恼的事情？
No, not as far as I know, sorry.
But you can pursue solutions outside the language.
For example, in Windows you can isolate the usage of one of the classes
to a dynamically linked library.
Or, for example, you can check whether the same functionality is
available from some higher quality libraries, which you should probably
do anyway -- using low-quality libraries will yield more and more
problems, and can force you to use less than good design.
A quality C++ library will use a namespace to greatly reduce the chance
of name collisions, so that''s one thing to look for.
