如何使用自定义类在 actionscript 3 中定义对象 [英] How to define an object in actionscript 3 using a custom class

问题描述

我的问题是我必须能够引用我的 Customer 对象中的某些字段.]

Hi my problem is i have to be able to reference certain fields inside my Customer object.]

我目前正在学习 AS3 并正在教授自定义课程，但我们被教导使用 toString 返回值的方法，我猜你可以调用它，我需要的是能够从数组中的对象调用一个字段来标识对象，即 name 字段，这是我的代码

I am studying AS3 at the moment and being taught custom classes, but we are taught to use the toString method of returning a value i guess you could call it, what i need is to be able to call one field to identify the object i.e. name field from the object in the array, here's my code

package valueObjects
{
public class Person
{
    //instance variables
    protected var name:String;
    protected var address:String;
    protected var phoneNo:String;   

    public function Person(n:String,a:String,p:String)
    {
        name=n;
        address=a;
        phoneNo=p;
    }

    public function toString():String
    {
        //returns string 
        return name+":"+address+":"+phoneNo;
    }
}

}

出于某种原因，它不会像这是

some reason it will not put that whole block of code together like THIS IS

那么现在我如何定义它而不是 toString 而是以对象形式??

So now how do i define it not toString but in object form ??

推荐答案

我认为您要做的是访问 name、address 和 phoneNo 来自不同类的变量?

I think what you are trying to do is access the name, address and phoneNo vars from a different class?

如果是这样，您必须将它们声明为 public 变量而不是 private 变量.

If so, you have to declare them as public vars instead of private vars.

public var name:String; //now this can be accessed from other classes:  thisClassInstance.name

如果你想让它们在其他类中只读，你必须使用 getter 方法:

If you want to have them read-only from other classes, you have to use a getter method:

protected var name_:String;  //local var name for full access;
public function get name():String {
    return name_; //this can be access by doing  thisClassInstance.name
}
