如何使用自定义类来定义在ActionScript 3的对象 [英] How to define an object in actionscript 3 using a custom class

问题描述

大家好，我的问题是我必须能够引用在我的客户对象的某些字段。]

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

我学习AS3的时刻，被教导自定义类，但是我们被教导要使用返回值，我想你可以把它的的toString 方法，有什么我需要的是能够调用一个字段来标识即名称从数组中的对象字段中的对象，这是我的code

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;
    }
}

}

由于某种原因，它不会把code表示整个街区在一起，就像 THIS IS

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

所以，现在我如何定义它不是的ToString但在对象的形式??

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

推荐答案

我认为你正在做什么是访问名称，地址和 PHONENO 从一个不同的类瓦尔？

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，你必须声明为公开瓦尔私人而不是 瓦尔。

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

如果你想拥有它们设置为只读从其他类，你必须使用一个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
}
