布尔值作为方法参数是不可接受的吗? [英] Are booleans as method arguments unacceptable?

问题描述

我的一位同事表示，布尔值作为方法参数是不可接受的.它们应由枚举代替.起初我没有看到任何好处，但他给了我一个例子.

A colleague of mine states that booleans as method arguments are not acceptable. They shall be replaced by enumerations. At first I did not see any benefit, but he gave me an example.

什么更容易理解?

file.writeData( data, true );

或者

enum WriteMode {
  Append,
  Overwrite
};

file.writeData( data, Append );

现在我明白了！;-)
这绝对是一个将枚举作为第二个参数使代码更具可读性的示例.

Now I got it! ;-)
This is definitely an example where an enumeration as second parameter makes the code much more readable.

那么，你对这个话题有什么看法?

So, what's your opinion on this topic?

推荐答案

布尔值表示是/否"的选择.如果要表示是/否"，则使用布尔值，它应该是不言自明的.

Boolean's represent "yes/no" choices. If you want to represent a "yes/no", then use a boolean, it should be self-explanatory.

但是，如果要在两个选项之间进行选择，而这两个选项都不是明确的是或否，那么枚举有时会更具可读性.

But if it's a choice between two options, neither of which is clearly yes or no, then an enum can sometimes be more readable.
