命名工厂功能 [英] Naming factory functions
问题描述
人们称他们的工厂功能为何？ ''new''不是一个选项
（是的，它可以重载但必须返回void *）。
上下文是：
class MyClass
{
public：
//工厂功能
static MyClass * new（int）;
//生成类的副本
虚拟MyClass * dup（）= 0;
//访问函数
virtual int whatever（int）= 0;
};
对我来说最有意义的是：
MyClass * mp = MyClass :: new（1）;
但是''new ''是不允许的。
工厂功能是否有准标准名称？无论什么
这个名字都不应该重复已知的信息
（MyClass :: newMyClass（）很傻）。 制作副本函数，dup（），
被合理地命名（好吧，我喜欢短名字）。
我想要一个单词，暗示返回的是一个指向一个新的
版本的类（''make''和''create''并不意味着对我来说）......

* Chris Croughton：
我想要一个暗示什么是return是一个指向类的新
[实例]的指针（''make''和''create''并不意味着对我来说）......
如果你想要一个结果的描述，那么一个动词不好，除非
结果是一个动作。
尝试''instance''或''instanceFrom''。
这些都是好名字，似乎正是你想要的。

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：usenet和电子邮件中最烦人的是什么？

make_new？

方法或函数是动词，它是做事。结果是
成为事物。
尝试''instance''或''instanceFrom''。
''instanceFrom（）''对我来说没什么意义。 ''newInstance（）''可能
工作，但是...
这些都是好名字，似乎正是你正在寻找的东西。
''instanciate（）''将是另一个，如果我使用长名称，则使用''复制（）''
。我想如果我正在使用''dup（）''那么我可以使用
''inst（）''作为缩写。
MyClass * p = Myclass :: inst（）;
MyClass * q = p-> dup（）;
谢谢，我用完了词库中的单词...

What do people call their factory functions? ''new'' is not an option
(yes, it can be overloaded but has to return void*).
The context is:
class MyClass
{
public:
// Factory functions
static MyClass* new(int);
// Produce a copy of the class
virtual MyClass* dup() = 0;
// Access functions
virtual int whatever(int) = 0;
};
To me it makes most sense to say:
MyClass* mp = MyClass::new(1);
but ''new'' isn''t allowed.
Are there any quasi-standard names for the factory functions? Whatever
the name it shouldn''t repeat information which is already known
(MyClass::newMyClass() is silly). The "make a copy" function, dup(),
is reasonably named (OK, I like short names).
I want a word which implies that what is returned is a pointer to a new
version of the class (''make'' and ''create'' don''t imply that to me)...

If you want a description of the result then a verb isn''t good, unless the
result is an action.
Try ''instance'' or ''instanceFrom''.
Those are good names and seem to be just what you''re looking for.

make_new?

A method or function is a verb, it''s a "doing thing". The result is a
"being thing".
Try ''instance'' or ''instanceFrom''.
''instanceFrom()'' doesn''t make much sense to me. ''newInstance()'' might
work, though...

''instanciate()'' would be another one, to go with ''duplicate()'' if I were
using long names. I suppose if I''m using ''dup()'' then I could use
''inst()'' as an abbreviation.
MyClass* p = Myclass::inst();
MyClass* q = p->dup();
Thanks, I was running out of words in the thesaurus...
