我写了一个单独的类来跟踪一些变量在我的应用程序。

I wrote a singleton class to keep track of some variables across my application.

我得到一个语法错误，我想不通，我敢肯定，我失去了一些东西简单，但它是那些日子之一。任何人看到的东西错了我的code？

I am getting a syntax error that I can't figure out, I am sure that I am missing something simple but it's been one of those days. Anyone see something wrong with my code?

该错误是1061：通过静态类型类引用调用可能未定义的方法的setResult

The error is 1061: Call to a possibly undefined method setResult through a reference with static type Class.

我在我的单例类的功能

public function setResult(resultNumber:int, value:int): void
    {
        switch(resultNumber)
        {
            case 2: { this.result2 = value; break; }
            case 3: { this.result3 = value; break; }
            case 4: { this.result4 = value; break; }
            case 5: { this.result5 = value; break; }
            case 6: { this.result6 = value; break; }
            case 7: { this.result7 = value; break; }
            case 8: { this.result8 = value; break; }
            case 9: { this.result9 = value; break; }
            case 10: { this.result10 = value; break; }
            case 11: { this.result11 = value; break; }
            case 12: { this.result12 = value; break; }
            case 13: { this.result13 = value; break; }
            case 14: { this.result14 = value; break; }
        }
    }

在我的MXML页我的函数调用

My function call in my mxml page

            if(chkBox1.selected == true)
            {
                utils.Calculation.setResult(2,1);
            }

在此先感谢您的帮助！

Thanks in advance for any help!

推荐答案

假设你单是计算类，你缺少你的getInstance调用？

Assuming you singleton is the Calculation class, are you missing your getInstance call?

utils.Calculation.getInstance().setResult(2, 1);

一个很好的动作Singleton模式：

A good actionscript singleton pattern:

package com.stackOverflow
{
    public class MySingleton
    {
        public function MySingleton(lock:Class)
        {
            if(lock != SingletonLock)
                throw new Error("This class cannot be instantiated, it is a singleton!");
        }
        private static var mySingleton:MySingleton;

        public static function getInstance():MySingleton{
            if(mySingleton==null)
                mySingleton = new MySingleton(SingletonLock);
            return mySingleton;
        }
        public function setResult(resultNumber:int, value:int): void{
        //...
        }
    }
}
class SingletonLock{}

编辑：的getInstance（）为例进行计算类：

getInstance() example for the Calculation class:

private static var calculation:Calculation;
public static function getInstance():Calculation{
    if(calculation==null)
        calculation = new Calculation(SingletonLock);
    return calculation;
}
