在哪里＆QUOT;适当＆QUOT;地方初始化AS3类变量

问题描述

是不是好来初始化AS3类在类的构造函数的变量？或者，我可以只初始化它们的默认值，当我宣布他们在我班上名列前茅？我问，因为当有大量的类变量，它宣布他们在一个地方，然后初始化它们在其他的时候，我可以很容易地在同一个地方做到既显得效率低下。这一个选项是比其他的，为什么呢？

更好

谢谢！

例如：

在初始化构造

 类Foo {
    VAR条：布尔
}

函数foo（）：无效{
    巴= TRUE;
}
 

或

通过声明初始化

 类Foo {
    VAR条：布尔=真;
}

函数foo（）：无效{
}
 

解决方案

我个人建议的初始化构造函数中的有两个原因：

1. 您不能初始化依赖于其他对象的无功的有已经在施工前创建的对象。
2. 它更容易找到和理解初始化code时，它的正常程序。尤其是当你（我）潜水回大类我还没有开了几个月。

Is it "better" to initialize AS3 class variables in the class constructor? Or can I just initialize them to their default value when I declare them at the top of my class? I ask because when there's a lot of class variables, it appears inefficient to declare them in one place and then initialize them in another when I could easily do both in the same place. It one option is better than the other, why?

Thanks!

eg:

initializing in constructor

class foo {
    var bar:Boolean
}

function foo():void {
    bar = true;
}

OR

initializing with the declaration

class foo {
    var bar:Boolean = true;
}

function foo():void {
}

解决方案

I personally recommend initialization inside the constructor for two reasons:

1. You cannot initialize objects that depend on other var objects having already been created before construction.
2. It's easier to locate and understand initialization code when it's properly procedural. Especially when you (I) dive back into big classes I haven't opened for months.
